+Subject: Bluetooth: hci_conn: fix potential UAF in set_cig_params_sync
+
+From: Pauli Virtanen <pav@iki.fi>
+
+[ Upstream commit a2639a7f0f5bf7d73f337f8f077c19415c62ed2c ]
+
+hci_conn lookup and field access must be covered by hdev lock in
+set_cig_params_sync, otherwise it's possible it is freed concurrently.
+
+Take hdev lock to prevent hci_conn from being deleted or modified
+concurrently. Just RCU lock is not suitable here, as we also want to
+avoid "tearing" in the configuration.

+Subject: bpf: Free reuseport cBPF prog after RCU grace period.
+
+From: Kuniyuki Iwashima <kuniyu@google.com>
+
+[ Upstream commit 18fc650ccd7fe3376eca89203668cfb8268f60df ]
+
+Eulgyu Kim reported the splat below with a repro. [0]
+
+The repro sets up a UDP reuseport group with a cBPF prog and
+replaces it with a new one while another thread is sending
+a UDP packet to the group.
+
+The reuseport prog is freed by sk_reuseport_prog_free().
+bpf_prog_put() is called for "e"BPF prog to destruct through
+multiple stages while cBPF prog is freed immediately by
+bpf_release_orig_filter() and bpf_prog_free().
+
+If a reuseport prog is detached from the setsockopt() path
+(reuseport_attach_prog() or reuseport_detach_prog()),
+sk_reuseport_prog_free() is called without waiting for RCU
+readers to complete, resulting in various bugs.
+
+Let's defer freeing the reuseport cBPF prog after one RCU
+grace period.
+
+Note "e"BPF prog is safe as is unless the fast path starts
+to touch fields destroyed in bpf_prog_put_deferred() and
+__bpf_prog_put_noref().

+
+From: Nathan Chancellor <nathan@kernel.org>
+
+commit 175db11786bde9061db526bf1ac5107d915f5163 upstream.
+
+Clang recently added support for -Wattribute-alias [1], which results in
+the same warnings that necessitated commit bee20031772a ("disable
+-Wattribute-alias warning for SYSCALL_DEFINEx()") for GCC.
+
+ kernel/time/itimer.c:325:1: error: alias and aliasee have different types 'long (unsigned int)' and 'long (typeof (__builtin_choose_expr((__builtin_types_compatible_p(typeof ((unsigned int)0), typeof (0LL)) || __builtin_types_compatible_p(typeof ((unsigned int)0), typeof (0ULL))), 0LL, 0L)))' (aka 'long (long)') [-Werror,-Wattribute-alias]

+
+Disable the warnings in the same way for clang-23 and newer. Disable the
+warning about unknown warning options to avoid breaking the build for
+versions of clang-23 that do not have -Wattribute-alias, such as ones
+deployed by vendors like Android or CI systems or when bisecting LLVM
+between llvmorg-23-init and release/23.x.

+Subject: hwmon: (pmbus/core) Protect regulator operations with mutex
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+[ Upstream commit 754bd2b4a084b90b5e7b630e1f423061a9b9b761 ]
+
+The regulator operations pmbus_regulator_get_voltage(),
+pmbus_regulator_set_voltage(), and pmbus_regulator_list_voltage()
+access PMBus registers and shared data but were not protected by
+the update_lock mutex. This could lead to race conditions.
+
+However, adding mutex protection directly to these functions causes
+a deadlock because pmbus_regulator_notify() (which calls
+regulator_notifier_call_chain()) is often called with the mutex
+already held (e.g., from pmbus_fault_handler()). If a regulator
+callback then calls one of the now-protected voltage functions,
+it will attempt to acquire the same mutex.
+
+Rework pmbus_regulator_notify() to utilize a worker function to
+send notifications outside of the mutex protection. Events are
+stored as atomics in a per-page bitmask and processed by the worker.
+
+Initialize the worker and its associated data during regulator
+registration, and ensure it is cancelled on device removal using
+devm_add_action_or_reset().
+
+While at it, remove the unnecessary include of linux/of.h.

+
+The root cause is as below:
+
+In the function rxe_create_qp, the function rxe_qp_from_init is called
+to create qp, if this function rxe_qp_from_init fails, rxe_cleanup will
+be called to handle all the allocated resources, including the timers:
+retrans_timer and rnr_nak_timer.
+
+The function rxe_qp_from_init calls the function rxe_qp_init_req to
+initialize the timers: retrans_timer and rnr_nak_timer.
+
+But these timers are initialized in the end of rxe_qp_init_req.
+If some errors occur before the initialization of these timers, this
+problem will occur.
+
+The solution is to check whether these timers are initialized or not.
+If these timers are not initialized, ignore these timers.

+Subject: USB: serial: mct_u232: fix memory corruption with small endpoint
+
+From: Johan Hovold <johan@kernel.org>
+
+commit 915b36d701950503c4ea0f6e314b10868e59fce3 upstream.
+
+The driver overrides the maximum transfer size for a specific device
+which only accepts 16 byte packets for its 32 byte bulk-out endpoint.
+
+Make sure to never increase the maximum transfer size to prevent slab
+corruption should a malicious device report a smaller endpoint max
+packet size than expected.
+
