    wifi: rtw88: pci: fix resource leak on failed NAPI setup

    In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: pci: fix resource leak on failed NAPI setup rtw_pci_probe() allocates PCI resources through rtw_pci_setup_resource() before it sets up NAPI. If rtw_pci_napi_init() fails, the error path jumps straight to err_pci_declaim and skips rtw_pci_destroy(), leaving the PCI resources allocated by rtw_pci_setup_resource() behind. Add a dedicated cleanup label for the NAPI setup failure path so probe destroys the PCI resources. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing current mainline k

    wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex mt7615_suspend() acquired the mt76 mutex and then called cancel_delayed_work_sync() on mac_work. mt7615_mac_work() acquires the same mutex via mt7615_mutex_acquire() at the top of the worker, so if mac_work is already running and blocked on the mutex, the suspend path deadlocks waiting for the work it holds the mutex against. Flush scan_work and mac_work before taking the mutex, matching the suspend paths in mt7921 and mt7925. scan_work only takes the mt76 spinlock, but moving it keeps the sequence consi

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy mt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver's dev->mt76.eeprom.data buffer at the offset reported by the MCU response (res->addr, a device-controlled __le32) without checking it against the buffer size. A malicious or malfunctioning device can report an arbitrary address and drive a 16-byte out-of-bounds write past eeprom.data.

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: cancel mlo_pm_work on stop mt7925 queues mlo_pm_work with a 5 second delay during multi-link power-save setup and never cancels it on the stop path. If the device is torn down inside that window, the work outlives the teardown and its timer fires afterwards, trying to queue onto the workqueue that is already gone: workqueue: cannot queue mt7925_mlo_pm_work [mt7925_common] on wq phy0 WARNING: kernel/workqueue.c:2283 at __queue_work+0x59/0xa0, CPU#1: swapper/1/0 call_timer_fn+0x2a/0x140 __run_timers+0x203/0x330 run_timer_softirq+0x86/0xf0 mt

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: bound the device EEPROM address before the EFUSE copy mt7996_mcu_get_eeprom() derives the destination of the EFUSE/EXT block copy from the address reported by the MCU response (event->addr, a device-controlled __le32) and clamps only the copy length, never the destination offset into dev->mt76.eeprom.data. A malicious or malfunctioning device can report an arbitrary address and drive an out-of-bounds write of up to MT7996_EXT_EEPROM_BLOCK_SIZE bytes past eeprom.data.

    wifi: mt76: mt7996: fix TX DMA mapping leak for AddBA req frames

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: fix TX DMA mapping leak for AddBA req frames mt7996/mt7992 hand the firmware a HW MAC-TXP for AddBA req action frames (MT_TXD7_MAC_TXD, set in mt7996_mac_write_txwi_80211()), but are otherwise FW-TXP devices. On tx free mt76_connac_txp_skb_unmap() therefore decodes the per-frame txp as a struct mt76_connac_fw_txp. For a MAC-TXP the fw_txp.nbuf byte aliases the AddBA TID word (MT_TXP1_TID_ADDBA), which is always zero, so the unmap loop runs zero times and the skb DMA mapping in buf[1] is never unmapped. buf[1].skip_unmap is set unconditionally, so the gen

    wifi: mt76: mt7996: validate default EEPROM firmware size

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: validate default EEPROM firmware size The default EEPROM firmware is parsed and copied as a full EEPROM without checking its length. A truncated file can make the driver read beyond the firmware buffer during variant validation or the fallback copy. Reject files shorter than MT7996_EEPROM_SIZE before parsing or copying the firmware.

    vsock/virtio: flush works in dependency order

    In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: flush works in dependency order virtio_vsock_remove() stops the virtqueues and then flushes each work item before freeing the enclosing virtio_vsock. The current order does not account for dependencies between those items: tx_work may queue send_pkt_work, and send_pkt_work may queue rx_work. In particular, send_pkt_work can set restart_rx and release tx_lock. The remove path can then stop the queues and flush rx_work before send_pkt_work queues it. Although the later send_pkt_work flush waits for that producer to finish, nothing waits for the newly queued r

    w1: ds28e17: reject an oversize length on an I2C block read

    In the Linux kernel, the following vulnerability has been resolved: w1: ds28e17: reject an oversize length on an I2C block read w1_f19_i2c_master_transfer() is the master_xfer for the DS28E17 1-Wire to I2C bridge. On an I2C_M_RECV_LEN read, it takes the length from the device. The downstream slave puts a length byte in buf[0]. The driver then reads that many bytes into buf[1] with w1_f19_i2c_read(). buf[0] is controlled by the device and can be 0 to 255. w1_f19_i2c_read() only rejects a zero count. The caller buffer is I2C_SMBUS_BLOCK_MAX + 2, so 34 bytes. A length above 32 makes the read run past it, up to about 222 bytes out of bounds.

    tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout

    In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout i2c_nuvoton_wait_for_stat() enables the IRQ before waiting for the interrupt handler to report a status change. If the wait times out, or is interrupted before the handler runs, the function returns without balancing the enable_irq() call. Disable the IRQ before leaving the failed wait path. Also preserve an interrupted wait's original error code instead of converting it to -ETIMEDOUT inside the helper.

    sysctl: move the "cad_pid" entry from pid_table[] to kern_reboot_table[]

    In the Linux kernel, the following vulnerability has been resolved: sysctl: move the "cad_pid" entry from pid_table[] to kern_reboot_table[] cad_pid is global, and kill_cad_pid() is only used in the root namespace. However, due to pid_table_root_permissions(), a non-root user can unshare pid/user namespaces and modify it from the child namespace. This makes no sense and is simply wrong. Move it to kern_reboot_table[] where it logically belongs; this ensures that only GLOBAL_ROOT_UID can read/modify this sysctl. Note that this patch doesn't preserve "#ifdef CONFIG_PROC_SYSCTL" around the "cad_pid"; CONFIG_PROC_SYSCTL selects CONFIG_SYSCTL

    In the Linux kernel, the following vulnerability has been resolved: smack: fix cred UAF in smack_file_send_sigiotask() When inspecting the credentials of another task, objective credentials (->real_cred, accessed with __task_cred()) must always be used. Accessing ->cred on a non-current task is forbidden unless that task is being created or destroyed; a task is allowed to change its own ->cred pointer with no synchronization, and changing ->cred should only affect the current syscall. smack_file_send_sigiotask() was accessing both sets of credentials: First tsk->cred, then __task_cred(tsk). Fix it, always access the objective credentials

    In the Linux kernel, the following vulnerability has been resolved: timekeeping: Check the return value of tk_get_aux_ts64 in __do_adjtimex() If the auxiliary clock is disabled during tk_get_aux_ts64() but is enabled before tks->clock_valid is checked, then uninitialized stackdata will be used in the calculations and indirectly leaked to userspace. The same race window also exists after this change and also for the core timekeeper. But in these cases the only effect would be incorrect adjustments and this is userspace's responsibility to avoid this.

    In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in oplock break notification smb2_oplock_break_noti() reads opinfo->conn without any lock and dereferences it after two allocations which may sleep. When the durable handle owning the oplock is disconnected, session_fd_check() clears opinfo->conn and drops its conn reference under ci->m_lock, and the last ksmbd_conn_put() frees the connection. A break triggered by another connection that races with the teardown can then resurrect the freed connection: ksmbd_conn_get() is a plain atomic_inc, and the queued break work later dereferences the stale c

This causes two issues: 1. Lockless TX paths (e.g. packet_snd in af_packet.c, ip6_finish_output2) read dev->hard_header_len without holding RTNL lock. Mutating hard_header_len dynamically under RTNL creates a data race where upper layers reserve insufficient headroom based on a stale hard_header_len, resultin
