+Subject: ALSA: ctxfi: Fix potential OOB access in audio mixer handling
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 61006c540cbdedea83b05577dc7fb7fa18fe1276 upstream.
+
+In the audio mixer handling code of ctxfi driver, the conf field is
+used as a kind of loop index, and it's referred in the index callbacks
+(amixer_index() and sum_index()).
+
+As spotted recently by fuzzers, the current code causes OOB access at
+those functions.
+| UBSAN: array-index-out-of-bounds in /build/reproducible-path/linux-6.17.8/sound/pci/ctxfi/ctamixer.c:347:48
+| index 8 is out of range for type 'unsigned char [8]'
+
+After the analysis, the cause was found to be the lack of the proper
+(re-)initialization of conj field.
+
+This patch addresses those OOB accesses by adding the proper
+initializations of the loop indices.

+Subject: ALSA: scarlett2: Fix buffer overflow in config retrieval
+
+From: Samasth Norway Ananda <samasth.norway.ananda@oracle.com>
+
+commit 6f5c69f72e50d51be3a8c028ae7eda42c82902cb upstream.
+
+The scarlett2_usb_get_config() function has a logic error in the
+endianness conversion code that can cause buffer overflows when
+count > 1.
+
+The code checks `if (size == 2)` where `size` is the total buffer size in
+bytes, then loops `count` times treating each element as u16 (2 bytes).
+This causes the loop to access `count * 2` bytes when the buffer only
+has `size` bytes allocated.
+
+Fix by checking the element size (config_item->size) instead of the
+total buffer size. This ensures the endianness conversion matches the
+actual element type.
+
+Fixes: ac34df733d2d ("ALSA: usb-audio: scarlett2: Update get_config to do endian conversion")

+Subject: ALSA: usb-audio: Fix use-after-free in snd_usb_mixer_free()
+
+From: Berk Cem Goksel <berkcgoksel@gmail.com>
+
+commit 930e69757b74c3ae083b0c3c7419bfe7f0edc7b2 upstream.
+
+When snd_usb_create_mixer() fails, snd_usb_mixer_free() frees
+mixer->id_elems but the controls already added to the card still
+reference the freed memory. Later when snd_card_register() runs,
+the OSS mixer layer calls their callbacks and hits a use-after-free read.
+
+Call trace:

+
+Fix by calling snd_ctl_remove() for all mixer controls before freeing
+id_elems. We save the next pointer first because snd_ctl_remove()
+frees the current element.

+Subject: arm64/fpsimd: signal: Allocate SSVE storage when restoring ZA
+
+From: Mark Rutland <mark.rutland@arm.com>
+
+commit ea8ccfddbce0bee6310da4f3fc560ad520f5e6b4 upstream.
+
+The code to restore a ZA context doesn't attempt to allocate the task's
+sve_state before setting TIF_SME. Consequently, restoring a ZA context
+can place a task into an invalid state where TIF_SME is set but the
+task's sve_state is NULL.
+
+In legitimate but uncommon cases where the ZA signal context was NOT
+created by the kernel in the context of the same task (e.g. if the task
+is saved/restored with something like CRIU), we have no guarantee that
+sve_state had been allocated previously. In these cases, userspace can
+enter streaming mode without trapping while sve_state is NULL, causing a
+later NULL pointer dereference when the kernel attempts to store the
+register state:

+Fix this by having restore_za_context() ensure that the task's sve_state
+is allocated, matching what we do when taking an SME trap. Any live
+SVE/SSVE state (which is restored earlier from a separate signal
+context) must be preserved, and hence this is not zeroed.

+Subject: arm64: Set __nocfi on swsusp_arch_resume()
+
+From: Zhaoyang Huang <zhaoyang.huang@unisoc.com>
+
+commit e2f8216ca2d8e61a23cb6ec355616339667e0ba6 upstream.
+
+A DABT is reported[1] on an android based system when resume from hiberate.
+This happens because swsusp_arch_suspend_exit() is marked with SYM_CODE_*()
+and does not have a CFI hash, but swsusp_arch_resume() will attempt to
+verify the CFI hash when calling a copy of swsusp_arch_suspend_exit().
+
+Given that there's an existing requirement that the entrypoint to
+swsusp_arch_suspend_exit() is the first byte of the .hibernate_exit.text
+section, we cannot fix this by marking swsusp_arch_suspend_exit() with
+SYM_FUNC_*(). The simplest fix for now is to disable the CFI check in
+swsusp_arch_resume().
+
+Mark swsusp_arch_resume() as __nocfi to disable the CFI check.

+Subject: can: ems_usb: ems_usb_read_bulk_callback(): fix URB memory leak
+
+From: Marc Kleine-Budde <mkl@pengutronix.de>
+
+commit 0ce73a0eb5a27070957b67fd74059b6da89cc516 upstream.
+
+Fix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:
+gs_usb_receive_bulk_callback(): fix URB memory leak").
+
+In ems_usb_open(), the URBs for USB-in transfers are allocated, added to
+the dev->rx_submitted anchor and submitted. In the complete callback
+ems_usb_read_bulk_callback(), the URBs are processed and resubmitted. In
+ems_usb_close() the URBs are freed by calling
+usb_kill_anchored_urbs(&dev->rx_submitted).
+
+However, this does not take into account that the USB framework unanchors
+the URB before the complete function is called. This means that once an
+in-URB has been completed, it is no longer anchored and is ultimately not
+released in ems_usb_close().
+
+Fix the memory leak by anchoring the URB in the
+ems_usb_read_bulk_callback() to the dev->rx_submitted anchor.

+Apparently we never actually filled these in, despite the fact that we do

+
+Since not having these filled in causes us to potentially forget to disable

+
+commit b8f15d1df2e73322e2112de21a4a7f3553c7fb60 upstream.
+
+The sensors IIS328DQ and H3LIS331DL share one configuration but
+H3LIS331DL has different gain parameters, configs therefore
+need to be split up.
+The gain parameters for the IIS328DQ are 0.98, 1.95 and 3.91,
+depending on the selected measurement range.
+
+See sensor manuals, chapter 2.1 "mechanical characteristics",
+parameter "Sensitivity".

+The mask setting is 5 bits wide for the ad9434

+
+From: Pei Xiao <xiaopei01@kylinos.cn>
+
+commit dbdb442218cd9d613adeab31a88ac973f22c4873 upstream.
+
+at91_adc_interrupt can call at91_adc_touch_data_handler function
+to start the work by schedule_work(&st->touch_st.workq).
+
+If we remove the module which will call at91_adc_remove to
+make cleanup, it will free indio_dev through iio_device_unregister but
+quite a bit later. While the work mentioned above will be used. The
+sequence of operations that may lead to a UAF bug is as follows:
+
+CPU0 CPU1
+
+ | at91_adc_workq_handler
+at91_adc_remove |
+iio_device_unregister(indio_dev) |
+//free indio_dev a bit later |
+ | iio_push_to_buffers(indio_dev)
+ | //use indio_dev
+
+Fix it by ensuring that the work is canceled before proceeding with
+the cleanup in at91_adc_remove.

+
+commit 81d5a5366d3c20203fb9d7345e1aa46d668445a2 upstream.
+
+The driver converts values read from the sensor from BE to CPU
+endianness in scd4x_read_meas(). The result is then pushed into the
+buffer in scd4x_trigger_handler(), so on LE architectures parsing the
+buffer using the reported BE type gave wrong results.
+
+scd4x_read_raw() which provides sysfs *_raw values is not affected, it
+used the values returned by scd4x_read_meas() without further
+conversion.

+The chip info for this variant (I2C, four channels, 14 bit, internal

+Subject: irqchip/gic-v3-its: Avoid truncating memory addresses
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit 8d76a7d89c12d08382b66e2f21f20d0627d14859 upstream.
+
+On 32-bit machines with CONFIG_ARM_LPAE, it is possible for lowmem
+allocations to be backed by addresses physical memory above the 32-bit
+address limit, as found while experimenting with larger VMSPLIT
+configurations.
+
+This caused the qemu virt model to crash in the GICv3 driver, which
+allocates the 'itt' object using GFP_KERNEL. Since all memory below
+the 4GB physical address limit is in ZONE_DMA in this configuration,
+kmalloc() defaults to higher addresses for ZONE_NORMAL, and the
+ITS driver stores the physical address in a 32-bit 'unsigned long'
+variable.
+
+Change the itt_addr variable to the correct phys_addr_t type instead,
+along with all other variables in this driver that hold a physical
+address.
+
+The gicv5 driver correctly uses u64 variables, while all other irqchip
+drivers don't call virt_to_phys or similar interfaces. It's expected that
+other device drivers have similar issues, but fixing this one is
+sufficient for booting a virtio based guest.

+Subject: leds: led-class: Only Add LED to leds_list when it is fully ready
+
+From: Hans de Goede <johannes.goede@oss.qualcomm.com>
+
+commit d1883cefd31752f0504b94c3bcfa1f6d511d6e87 upstream.
+
+Before this change the LED was added to leds_list before led_init_core()
+gets called adding it the list before led_classdev.set_brightness_work gets
+initialized.
+
+This leaves a window where led_trigger_register() of a LED's default
+trigger will call led_trigger_set() which calls led_set_brightness()
+which in turn will end up queueing the *uninitialized*
+led_classdev.set_brightness_work.
+
+This race gets hit by the lenovo-thinkpad-t14s EC driver which registers
+2 LEDs with a default trigger provided by snd_ctl_led.ko in quick
+succession. The first led_classdev_register() causes an async modprobe of
+snd_ctl_led to run and that async modprobe manages to exactly hit
+the window where the second LED is on the leds_list without led_init_core()
+being called for it, resulting in:

+rtsx_pci_sdmmc does not have an sdmmc_card_busy function, so any voltage

+
+From: Jeongjun Park <aha310510@gmail.com>
+
+commit ba1096c315283ee3292765f6aea4cca15816c4f7 upstream.
+
+In nr_route_frame(), old_skb is immediately freed without checking if
+nr_neigh->ax25 pointer is NULL. Therefore, if nr_neigh->ax25 is NULL,
+the caller function will free old_skb again, causing a double-free bug.
+
+Therefore, to prevent this, we need to modify it to check whether
+nr_neigh->ax25 is NULL before freeing old_skb.

+Subject: octeontx2: Fix otx2_dma_map_page() error return code
+
+From: Thomas Fourier <fourier.thomas@gmail.com>
+
+commit d998b0e5afffa90d0f03770bad31083767079858 upstream.
+
+0 is a valid DMA address [1] so using it as the error value can lead to
+errors. The error value of dma_map_XXX() functions is DMA_MAPPING_ERROR
+which is ~0. The callers of otx2_dma_map_page() use dma_mapping_error()
+to test the return value of otx2_dma_map_page(). This means that they
+would not detect an error in otx2_dma_map_page().
+
+Make otx2_dma_map_page() return the raw value of dma_map_page_attrs().

+
+of_find_node_by_path() returns a device_node with its refcount

+continues to the next iteration without calling of_node_put(), causing

+Add of_node_put(np) before continue on both error paths to properly

+
+commit 48e6a9c4a20870e09f85ff1a3628275d6bce31c0 upstream.
+
+Calling of_platform_populate() without a match table will only populate
+the immediate child nodes under /firmware. This is usually fine, but in
+the case of something like a "simple-mfd" node such as
+"raspberrypi,bcm2835-firmware", those child nodes will not be populated.
+And subsequent calls won't work either because the /firmware node is
+marked as processed already.
+
+Switch the call to of_platform_default_populate() to solve this problem.
+It should be a nop for existing cases.

+commit 91dcfae0ff2b9b9ab03c1ec95babaceefbffb9f4 upstream.
+
+By default when users program perf to sample branch instructions
+(PERF_COUNT_HW_BRANCH_INSTRUCTIONS) with a sample period of 1, perf
+interprets this as a special case and enables BTS (Branch Trace Store)
+as an optimization to avoid taking an interrupt on every branch.
+
+Since BTS doesn't virtualize, this optimization doesn't make sense when
+the request originates from a guest. Add an additional check that
+prevents this optimization for virtualized events (exclude_host).

+Subject: platform/x86: hp-bioscfg: Fix automatic module loading
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Mario Limonciello <mario.limonciello@amd.com>
+
+commit 467d4afc6caa64b84a6db1634f8091e931f4a7cb upstream.
+
+hp-bioscfg has a MODULE_DEVICE_TABLE with a GUID in it that looks
+plausible, but the module doesn't automatically load on applicable
+systems.
+
+This is because the GUID has some lower case characters and so it
+doesn't match the modalias during boot. Update the GUIDs to be all
+uppercase.

+Subject: pmdomain: imx8m-blk-ctrl: Remove separate rst and clk mask for 8mq vpu
+
+From: Ming Qian <ming.qian@oss.nxp.com>
+
+commit 3de49966499634454fd59e0e6fecd50baab7febd upstream.
+
+For i.MX8MQ platform, the ADB in the VPUMIX domain has no separate reset
+and clock enable bits, but is ungated and reset together with the VPUs.
+So we can't reset G1 or G2 separately, it may led to the system hang.
+Remove rst_mask and clk_mask of imx8mq_vpu_blk_ctl_domain_data.
+Let imx8mq_vpu_power_notifier() do really vpu reset.

+Subject: s390/ap: Fix wrong APQN fill calculation
+
+From: Harald Freudenberger <freude@linux.ibm.com>
+
+commit 3317785a8803db629efc759d811d0f589d3a0b2d upstream.
+
+The upper limit of the firmware queue fill state for each APQN
+is reported by the hwinfo.qd field. This field shows the
+numbers 0-7 for 1-8 queue spaces available. But the exploiting
+code assumed the real boundary is stored there and thus stoppes
+queuing in messages one tick too early.
+
+Correct the limit calculation and thus offer a boost
+of 12.5% performance for high traffic on one APQN.

+
+From: Johan Hovold <johan@kernel.org>
+
+commit 9391380eb91ea5ac792aae9273535c8da5b9aa01 upstream.
+
+Slimbus devices can be allocated dynamically upon reception of
+report-present messages.
+
+Make sure to drop the reference taken when looking up already registered
+devices.
+
+Note that this requires taking an extra reference in case the device has
+not yet been registered and has to be allocated.

+Subject: tracing: Fix crash on synthetic stacktrace field usage
+
+From: Steven Rostedt <rostedt@goodmis.org>
+
+commit 90f9f5d64cae4e72defd96a2a22760173cb3c9ec upstream.
+
+When creating a synthetic event based on an existing synthetic event that
+had a stacktrace field and the new synthetic event used that field a
+kernel crash occurred:
+
+ ~# cd /sys/kernel/tracing
+ ~# echo 's:stack unsigned long stack[];' > dynamic_events
+ ~# echo 'hist:keys=prev_pid:s0=common_stacktrace if prev_state & 3' >> events/sched/sched_switch/trigger
+ ~# echo 'hist:keys=next_pid:s1=$s0:onmatch(sched.sched_switch).trace(stack,$s1)' >> events/sched/sched_switch/trigger
+
+The above creates a synthetic event that takes a stacktrace when a task
+schedules out in a non-running state and passes that stacktrace to the
+sched_switch event when that task schedules back in. It triggers the
+"stack" synthetic event that has a stacktrace as its field (called "stack").
+
+ ~# echo 's:syscall_stack s64 id; unsigned long stack[];' >> dynamic_events
+ ~# echo 'hist:keys=common_pid:s2=stack' >> events/synthetic/stack/trigger
+ ~# echo 'hist:keys=common_pid:s3=$s2,i0=id:onmatch(synthetic.stack).trace(syscall_stack,$i0,$s3)' >> events/raw_syscalls/sys_exit/trigger
+
+The above makes another synthetic event called "syscall_stack" that
+attaches the first synthetic event (stack) to the sys_exit trace event and
+records the stacktrace from the stack event with the id of the system call
+that is exiting.
+
+When enabling this event (or using it in a historgram):
+
+ ~# echo 1 > events/synthetic/syscall_stack/enable
+
+Produces a kernel crash!

+treated as a normal field and not as a dynamic event that it is.
+
+In trace_event_raw_event_synth() the event is field is still treated as a
+dynamic array, but the retrieval of the data is considered a normal field,
+and the reference is just the meta data:
+
+// Meta data is retrieved instead of a dynamic array
+ str_val = (char *)(long)var_ref_vals[val_idx];
+
+// Then when it tries to process it:
+ len = *((unsigned long *)str_val) + 1;
+
+It triggers a kernel page fault.
+
+To fix this, first when defining the fields of the first synthetic event,
+set the filter type to FILTER_STACKTRACE. This is used later by the second
+synthetic event to know that this field is a stacktrace. When creating
+the field of the new synthetic event, have it use this FILTER_STACKTRACE
+to know to create a stacktrace field to copy the stacktrace into.

+Subject: uacce: ensure safe queue release with state management
+
+From: Chenghai Huang <huangchenghai2@huawei.com>
+
+commit 26c08dabe5475d99a13f353d8dd70e518de45663 upstream.
+
+Directly calling `put_queue` carries risks since it cannot
+guarantee that resources of `uacce_queue` have been fully released
+beforehand. So adding a `stop_queue` operation for the
+UACCE_CMD_PUT_Q command and leaving the `put_queue` operation to
+the final resource release ensures safety.
+
+Queue states are defined as follows:
+- UACCE_Q_ZOMBIE: Initial state
+- UACCE_Q_INIT: After opening `uacce`
+- UACCE_Q_STARTED: After `start` is issued via `ioctl`
+
+When executing `poweroff -f` in virt while accelerator are still
+working, `uacce_fops_release` and `uacce_remove` may execute
+concurrently. This can cause `uacce_put_queue` within
+`uacce_fops_release` to access a NULL `ops` pointer. Therefore, add
+state checks to prevent accessing freed pointers.

+
+From: Wenkai Lin <linwenkai6@hisilicon.com>
+
+commit a3bece3678f6c88db1f44c602b2a63e84b4040ac upstream.
+
+When cdev_device_add fails, it internally releases the cdev memory,
+and if cdev_device_del is then executed, it will cause a hang error.
+To fix it, we check the return value of cdev_device_add() and clear
+uacce->cdev to avoid calling cdev_device_del in the uacce_remove.

+Subject: uacce: fix isolate sysfs check condition
+
+From: Chenghai Huang <huangchenghai2@huawei.com>
+
+commit 98eec349259b1fd876f350b1c600403bcef8f85d upstream.
+
+uacce supports the device isolation feature. If the driver
+implements the isolate_err_threshold_read and
+isolate_err_threshold_write callback functions, uacce will create
+sysfs files now. Users can read and configure the isolation policy
+through sysfs. Currently, sysfs files are created as long as either
+isolate_err_threshold_read or isolate_err_threshold_write callback
+functions are present.
+
+However, accessing a non-existent callback function may cause the
+system to crash. Therefore, intercept the creation of sysfs if
+neither read nor write exists; create sysfs if either is supported,
+but intercept unsupported operations at the call site.

+Subject: uacce: implement mremap in uacce_vm_ops to return -EPERM
+
+From: Yang Shen <shenyang39@huawei.com>
+
+commit 02695347be532b628f22488300d40c4eba48b9b7 upstream.
+
+The current uacce_vm_ops does not support the mremap operation of
+vm_operations_struct. Implement .mremap to return -EPERM to remind
+users.
+
+The reason we need to explicitly disable mremap is that when the
+driver does not implement .mremap, it uses the default mremap
+method. This could lead to a risk scenario:
+
+An application might first mmap address p1, then mremap to p2,
+followed by munmap(p1), and finally munmap(p2). Since the default
+mremap copies the original vma's vm_private_data (i.e., q) to the
+new vma, both munmap operations would trigger vma_close, causing
+q->qfr to be freed twice(qfr will be set to null here, so repeated
+release is ok).

+The struct ieee80211_vif contains trailing space for vif driver data,
+when struct ieee80211_vif is allocated, the total memory size that is
+allocated is sizeof(struct ieee80211_vif) + size of vif driver data.
+The size of vif driver data is set by each WiFi driver as needed.
+
+The RSI911x driver does not set vif driver data size, no trailing space
+for vif driver data is therefore allocated past struct ieee80211_vif .
+The RSI911x driver does however use the vif driver data to store its
+vif driver data structure "struct vif_priv". An access to vif->drv_priv
+leads to access out of struct ieee80211_vif bounds and corruption of
+some memory.
+
+In case of the failure observed locally, rsi_mac80211_add_interface()
+would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv;
+vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member
+struct list_head new_flows . The flow = list_first_entry(head, struct
+fq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogus
+address, which when accessed causes a crash.
+
+The trigger is very simple, boot the machine with init=/bin/sh , mount
+devtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1",
+"ip link set wlan0 down" and the crash occurs.
+
+Fix this by setting the correct size of vif driver data, which is the
+size of "struct vif_priv", so that memory is allocated and the driver
+can store its driver data in it, instead of corrupting memory around
+it.
