    wifi: ath10k: snoc: use memcpy_fromio() for MSA ramdump

    In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: snoc: use memcpy_fromio() for MSA ramdump On WCN3990/SNOC the MSA region is mapped with devm_memremap(MEMREMAP_WT). On arm64 such a mapping is not Normal-cacheable, so unaligned accesses to it are not permitted. ath10k_msa_dump_memory() copies the region with a plain memcpy(), whose optimized __pi_memcpy_generic implementation issues wide/unaligned loads. This triggers an alignment fault (FSC=0x21) Oops in ath10k_snoc_fw_crashed_dump() while collecting the devcoredump: Unable to handle kernel paging request ...

    arm64: ptrace: Keep 'orig_x0' in-sync with x0 on syscall entry

    In the Linux kernel, the following vulnerability has been resolved: arm64: ptrace: Keep 'orig_x0' in-sync with x0 on syscall entry Commit e057b9477232 ("arm64: syscall: Ensure saved x0 is kept in-sync with tracer updates") attempted to resolve a long-standing issue with syscall entry tracing, where a tracer is able to manipulate the first syscall argument without being subjected to seccomp or audit checking. Unfortunately, that fix was incomplete [1], as it failed to update 'orig_x0' between a tracer updating x0 during a seccomp ptrace exit (SECCOMP_RET_TRACE) and the seccomp filter being re-evaluated. Rather than add hooks to the core se

    wifi: nl80211: clean up color-change beacon data on errors

    In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: clean up color-change beacon data on errors nl80211_color_change() calls nl80211_parse_beacon() for the beacon_next template, which can allocate params.beacon_next.mbssid_ies and .rnr_ies. A parsing failure returned directly instead of using the out: cleanup, leaking any allocations completed before the error. Allocate the nested attribute table before parsing beacon_next. Its allocation failure can then return before beacon data exists, while a later parsing failure uses out: to release the parsed data.

    wifi: brcmfmac: fix P2P action frame handling without device vif

    In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: fix P2P action frame handling without device vif Some P2P action frame paths assume the P2P device vif is always available. That is not true when userspace sends non-P2P public action frames through the primary interface, or when action-frame abort runs after the P2P device vif has not been created. Fall back to the primary vif when aborting an action frame without a P2P device vif, and guard P2P device saved IE access before using it for peer channel search.

    wifi: cfg80211: stop PMSR before P2P and NAN teardown

    In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: stop PMSR before P2P and NAN teardown PMSR request teardown must abort active measurements while the wireless_dev is still present in the driver. cfg80211_leave_locked() and cfg80211_stop_pd() already do this before invoking the driver's stop callback, but cfg80211_stop_p2p_device() and cfg80211_stop_nan() do not. Those helpers are also called directly by nl80211, rfkill shutdown, and wireless_dev unregister paths. If one of these paths stops a P2P device or NAN interface with a pending request, it removes the mac80211 subinterface from the driver first. Su

    firmware: coreboot: Validate table bounds

    In the Linux kernel, the following vulnerability has been resolved: firmware: coreboot: Validate table bounds The existing coreboot_table_populate() bounds checks limit individual entries to the mapped length. However, coreboot_table_probe() replaces the platform resource length with header and table sizes supplied by firmware before mapping the full table. A malformed table can overflow the 32-bit size addition or advertise an extent beyond the resource, causing the driver to map and parse memory outside the resource. A resource shorter than the fixed header is also mapped as though it contained a complete header. Reject resources shor

    serial: core: do fallible allocations before the console can be registered

    In the Linux kernel, the following vulnerability has been resolved: serial: core: do fallible allocations before the console can be registered serial_core_add_one_port() allocates uport->tty_groups after uart_configure_port(), which may register the console. If the allocation fails, the driver unwinds the port while its console remains registered. The earlier uport->name allocation has a related failure path that leaves state->uart_port linked to a port being freed. Failslab reproduced a NULL dereference in PL011 console output and a KASAN use-after-free in i.MX console output after failed binds. Allocate the name and tty_groups before li

    serial: core: clear freed pointers on uart_register_driver() failure

    In the Linux kernel, the following vulnerability has been resolved: serial: core: clear freed pointers on uart_register_driver() failure uart_register_driver() leaves drv->state pointing to freed memory when tty_alloc_driver() fails. If tty_register_driver() fails, drv->tty_driver also retains a pointer after its reference is dropped. Drivers that use drv->state as an "already registered" flag can then skip registration on the next probe and pass the freed state to uart_add_one_port(). This issue was found with failslab on QEMU's raspi1ap board by failing registration and binding the PL011 port again. Clear both pointers on their failure

    tty: skip cdev_del() when no cdev is registered

    In the Linux kernel, the following vulnerability has been resolved: tty: skip cdev_del() when no cdev is registered TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdev_del(), causing a NULL-pointer dereference. Only delete the cdev when the slot is not NULL.

    dm-integrity: replace forgeable discard filler with a keyed sector marker

    In the Linux kernel, the following vulnerability has been resolved: dm-integrity: replace forgeable discard filler with a keyed sector marker The discard-block check in dm_integrity_rw_tag() treats a stored tag of all 0xf6 bytes (DISCARD_FILLER) as proof a block was discarded and skips HMAC verification. allow_discards is only accepted in dm-integrity's standalone mode. An attacker with raw write access to the backing device, but without the integrity key, can stamp any block with an all-0xf6 tag and have it served as authentic. Add a new "allow_discards_keyed" target argument that marks discarded blocks with a keyed checksum of (salt || s

    HID: logitech-hidpp: Fix FF device cleanup on init failure

    In the Linux kernel, the following vulnerability has been resolved: HID: logitech-hidpp: Fix FF device cleanup on init failure hidpp_ff_init() creates the input force-feedback device with input_ff_create(), then allocates the HID++ FF private data, effect ID array, and workqueue. If any of those allocations fail after input_ff_create() succeeds, the function returns an error without destroying the FF device. Add an unwind path that frees the private allocations made by hidpp_ff_init() and calls input_ff_destroy() for failures after input_ff_create() succeeds.

    HID: synchronize input before cleaning up a failed probe

    In the Linux kernel, the following vulnerability has been resolved: HID: synchronize input before cleaning up a failed probe hid_device_io_start() allows reports to run concurrently with probe. If the probe subsequently fails, __hid_device_probe() releases driver resources and clears hdev->driver without first excluding those report callbacks. For example, a report may enter hidraw_report_event() while the failure path frees the associated hidraw object, leading to a use-after-free when the report takes the object's list lock. Stop input before performing failed-probe cleanup. This reacquires driver_input_lock and waits for any report cal

    phonet: pep: do not write beyond optlen in getsockopt

    In the Linux kernel, the following vulnerability has been resolved: phonet: pep: do not write beyond optlen in getsockopt pep_getsockopt() clamps the reported length to the caller's buffer with min_t(), but then stores the value with put_user(val, (int __user *) optval), which always writes sizeof(int) bytes. A getsockopt() call with an optlen smaller than sizeof(int) thus reports the clamped length yet writes a full int, one to three bytes past the user buffer. Write the value with copy_to_user() bounded by len, so at most optlen bytes are copied, matching the length reported back to userspace.

    In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix race between policy activation and blkg destruction When switching an IO scheduler on a block device, blkcg_activate_policy() allocates blkg_policy_data (pd) for all blkgs attached to the queue. However, blkcg_activate_policy() may race with concurrent blkcg deletion, leading to use-after-free and memory leak issues. The use-after-free occurs in the following race: T1 (blkcg_activate_policy): - Successfully allocates pd for blkg1 (loop0->queue, blkcgA) - Fails to allocate pd for blkg2 (loop0->queue, blkcgB) - Enters the enomem rollback path to releas
