+Subject: batman-adv: fix OOB read/write in network-coding decode
+
+From: Stanislav Fort <stanislav.fort@aisle.com>
+
+commit d77b6ff0ce35a6d0b0b7b9581bc3f76d041d4087 upstream.
+
+batadv_nc_skb_decode_packet() trusts coded_len and checks only against
+skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing
+payload headroom, and the source skb length is not verified, allowing an
+out-of-bounds read and a small out-of-bounds write.
+
+Validate that coded_len fits within the payload area of both destination
+and source sk_buffs before XORing.

+Subject: cifs: prevent NULL pointer dereference in UTF16 conversion
+
+From: Makar Semyonov <m.semenov@tssltd.ru>
+
+commit 70bccd9855dae56942f2b18a08ba137bb54093a0 upstream.
+
+There can be a NULL pointer dereference bug here. NULL is passed to
+__cifs_sfu_make_node without checks, which passes it unchecked to
+cifs_strndup_to_utf16, which in turn passes it to
+cifs_local_to_utf16_bytes where '*from' is dereferenced, causing a crash.
+
+This patch adds a check for NULL 'src' in cifs_strndup_to_utf16 and
+returns NULL early to prevent dereferencing NULL pointer.

+Subject: drm/amdgpu: drop hw access in non-DC audio fini
+
+From: Alex Deucher <alexander.deucher@amd.com>
+
+commit 71403f58b4bb6c13b71c05505593a355f697fd94 upstream.
+
+We already disable the audio pins in hw_fini so
+there is no need to do it again in sw_fini.

+Subject: net: pcs: rzn1-miic: Correct MODCTRL register offset
+
+From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
+
+commit a7195a3d67dace056af7ca65144a11874df79562 upstream.
+
+Correct the Mode Control Register (MODCTRL) offset for RZ/N MIIC.
+According to the R-IN Engine and Ethernet Peripherals Manual (Rev.1.30)
+[0], Table 10.1 "Ethernet Accessory Register List", MODCTRL is at offset
+0x8, not 0x20 as previously defined.
+
+Offset 0x20 actually maps to the Port Trigger Control Register (PTCTRL),
+which controls PTP_MODE[3:0] and RGMII_CLKSEL[4]. Using this incorrect
+definition prevented the driver from configuring the SW_MODE[4:0] bits
+in MODCTRL, which control the internal connection of Ethernet ports. As
+a result, the MIIC could not be switched into the correct mode, leading
+to link setup failures and non-functional Ethernet ports on affected
+systems.

+Subject: ocfs2: prevent release journal inode after journal shutdown
+
+From: Edward Adam Davis <eadavis@qq.com>
+
+commit f46e8ef8bb7b452584f2e75337b619ac51a7cadf upstream.
+
+Before calling ocfs2_delete_osb(), ocfs2_journal_shutdown() has already
+been executed in ocfs2_dismount_volume(), so osb->journal must be NULL.
+Therefore, the following calltrace will inevitably fail when it reaches
+jbd2_journal_release_jbd_inode().
+
+ocfs2_dismount_volume()->
+  ocfs2_delete_osb()->
+    ocfs2_free_slot_info()->
+      __ocfs2_free_slot_info()->
+        evict()->
+          ocfs2_evict_inode()->
+            ocfs2_clear_inode()->
+             jbd2_journal_release_jbd_inode(osb->journal->j_journal,
+
+Adding osb->journal checks will prevent null-ptr-deref during the above
+execution path.

+
+Prevents instant wakeup ~1s after suspend.
+
+It seems to be kernel/system dependent if the IRQ actually manages to wake
+the system every time or if it gets ignored (and everything works as
+expected).

+Subject: proc: fix missing pde_set_flags() for net proc files
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: wangzijie <wangzijie1@honor.com>
+
+commit 2ce3d282bd5050fca8577defeff08ada0d55d062 upstream.
+
+To avoid potential UAF issues during module removal races, we use
+pde_set_flags() to save proc_ops flags in PDE itself before
+proc_register(), and then use pde_has_proc_*() helpers instead of directly
+dereferencing pde->proc_ops->*.
+
+However, the pde_set_flags() call was missing when creating net related
+proc files.  This omission caused incorrect behavior which FMODE_LSEEK was
+being cleared inappropriately in proc_reg_open() for net proc files.  Lars
+reported it in this link[1].
+
+Fix this by ensuring pde_set_flags() is called when register proc entry,
+and add NULL check for proc_ops in pde_set_flags().
+
+[wangzijie1@honor.com: stash pde->proc_ops in a local const variable, per Christian]

+Subject: sched: Fix sched_numa_find_nth_cpu() if mask offline
+
+From: Christian Loehle <christian.loehle@arm.com>
+
+commit 5ebf512f335053a42482ebff91e46c6dc156bf8c upstream.
+
+sched_numa_find_nth_cpu() uses a bsearch to look for the 'closest'
+CPU in sched_domains_numa_masks and given cpus mask. However they
+might not intersect if all CPUs in the cpus mask are offline. bsearch
+will return NULL in that case, bail out instead of dereferencing a
+bogus pointer.
+
+The previous behaviour lead to this bug when using maxcpus=4 on an
+rk3399 (LLLLbb) (i.e. booting with all big CPUs offline):

+Subject: scsi: lpfc: Fix buffer free/clear order in deferred receive path
+
+From: John Evans <evans1210144@gmail.com>
+
+commit 9dba9a45c348e8460da97c450cddf70b2056deb3 upstream.
+
+Fix a use-after-free window by correcting the buffer release sequence in
+the deferred receive path. The code freed the RQ buffer first and only
+then cleared the context pointer under the lock. Concurrent paths (e.g.,
+ABTS and the repost path) also inspect and release the same pointer under
+the lock, so the old order could lead to double-free/UAF.
+
+Note that the repost path already uses the correct pattern: detach the
+pointer under the lock, then free it after dropping the lock. The
+deferred path should do the same.

+From: Bjorn Andersson <bjorn.andersson@oss.qualcomm.com>
+
+commit 25daf9af0ac1bf12490b723b5efaf8dcc85980bc upstream.
+
+Firmware that doesn't provide section headers leave both e_shentsize and
+e_shnum 0, which obvious isn't compatible with the newly introduced
+stricter checks.
+
+Make the section-related checks conditional on either of these values
+being non-zero.

+Subject: wifi: mwifiex: Initialize the chan_stats array to zero
+
+From: Qianfeng Rong <rongqianfeng@vivo.com>
+
+commit 0e20450829ca3c1dbc2db536391537c57a40fe0b upstream.
+
+The adapter->chan_stats[] array is initialized in
+mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out
+memory.  The array is filled in mwifiex_update_chan_statistics()
+and then the user can query the data in mwifiex_cfg80211_dump_survey().
+
+There are two potential issues here.  What if the user calls
+mwifiex_cfg80211_dump_survey() before the data has been filled in.
+Also the mwifiex_update_chan_statistics() function doesn't necessarily
+initialize the whole array.  Since the array was not initialized at
+the start that could result in an information leak.
+
+Also this array is pretty small.  It's a maximum of 900 bytes so it's
+more appropriate to use kcalloc() instead vmalloc().
