In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix buffer overflow during vBIOS update Clamp the buffer postion to write by setting the bin attribute to the maximum buffer size so that VFS layer will block the out-of-bounds accessing.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but released in gfx_v9_0_hw_fini(), so the put site has to query amdgpu_irq_enabled() because the get is skipped on SR-IOV VF. ras_late_init / ras_fini have no suspend counterpart, so move the put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a matching ras_suspend callback that is invoked from amdgpu_…

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix SMI event cross-process information leak kfd_smi_ev_enabled() skips the suser privilege check when pid=0. PROCESS_START, PROCESS_END, and VMFAULT events are emitted with pid=0 while carrying another process's PID and command name, so any /dev/kfd user in the render group can monitor all GPU workloads. Pass the target process PID into kfd_smi_event_add() for these events so the existing per-client filter restricts delivery to the …

In the Linux kernel, the following vulnerability has been resolved: pds_core: quiesce DMA before freeing resources pdsc_teardown() frees DMA buffers but does not disable bus mastering, leaving the device able to perform DMA after the buffers are freed. This can lead to use-after-free if the device writes to freed memory. Add pci_clear_master() to pdsc_teardown() to disable bus mastering before freeing resources, ensuring all DMA is quiesced. Add pci_set_master() to pdsc_setup() to re-enable bus mastering, which…

In the Linux kernel, the following vulnerability has been resolved: nvme-fc: Do not cancel requests in io target before it is initialized A new nvme-fc controller in CONNECTING state sees admin request timeout schedules ctrl->ioerr_work to abort inflight requests. This ends up calling __nvme_fc_abort_outstanding_ios() which aborts requests in both admin and io tagsets. In case fc_ctrl->tag_set was not initialized we see the warning below. This is because ctrl.queue_count is initialized early in nvme_fc_alloc_ctrl…

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix races in cifsd thread creation The cifsd demultiplex thread can run and access tcp_ses before the parent thread has finished populating tcp_ses, which the worker thread accesses locklessly. Also, the kthread_run macro may start the thread before returning the thread pointer. Because the pointer is part of the structure that the thread can access, if the kernel is preempted after the thread is spawned, but before the thread point…

In the Linux kernel, the following vulnerability has been resolved: exfat: fix handling of damaged volume in exfat_create_upcase_table() When the size of the upcase table is set to zero in the dentry for any reason(e.g. corrupted media or misbehaving device), an integer overflow causes the module to loop indefinitely. If the size of the upcase table is read zero, do not attempt to load the table. Instead, fallback to loading the default upcase table. If the size of the upcase table is zero or no upcase table is …

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Let driver decide buffer size at AMDKFD_IOC_GET_DMABUF_INFO ioctl amdkfd driver needs allocate buffer to return bo metadata to user space. The buffer size is controlled by user currently. It is a potential security issue that hostile value (e.g. 2 GiB) lets any render-group user trigger order-MAX allocation/OOM in kernel context. This patch first finds bo metadata size. If the size is smaller than user provided value drive can safely…

In the Linux kernel, the following vulnerability has been resolved: perf: Fix addr_filter_ranges lifetime Lee Jia Jie reported that since event::addr_filter_ranges is used under RCU, it should be RCU freed.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: ibss: wait for in-flight TX on disconnect While leaving an IBSS in ieee80211_ibss_disconnect() mac80211 flushes stations, turns the carrier off and immediately tells the driver to leave as well. While there may be synchronize_net() in station flush and in this code later, packets can still be transmitted due to cross-CPU race conditions after carrier off is set. Therefore, it's possible for a race to happen where a TX to the drive…

In the Linux kernel, the following vulnerability has been resolved: smb/client: zero-initialize stack-allocated cifs_open_info_data Stack-allocated cifs_open_info_data may contain random data. This can make some fields have wrong value if they are not set later.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: pcie: null RX pointers after free When iwl_pcie_tx_init() fails after RX init, nic init unwinds via iwl_pcie_rx_free(). The freed RX members stayed non-NULL on the live transport object, so later teardown or retry could touch stale RX state. Set rx_pool, global_table, rxq, and alloc_page to NULL after free to make repeated cleanup and retry paths safe.

In the Linux kernel, the following vulnerability has been resolved: smb/client: flush dirty data before punching a hole Punching a hole after a large buffered write may leave the range reported as data. Reproduce it with: xfs_io -f \ -c "pwrite -b 3m -S 0x61 0 3m" \ -c "fpunch 1m 1m" \ -c "seek -h 0" \ -c "seek -d 1m" \ /mnt/test/repro Punching 1 MiB at offset 1 MiB should produce: 0 1 MiB 2 MiB 3 MiB | DATA | HOLE | DATA | EOF Instead, the entire f…

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: validate TX_CMD response layout TX_CMD parsing uses frame_count to walk status entries and then read the trailing SCD SSN. Make the minimum-length check follow that exact runtime layout calculation before parsing the payload. For new TX API, reject TX_CMD responses with frame_count != 1 and warn/return in the aggregation handler to document that aggregated accounting is expected via BA notifications.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix a possible underflow We shouldn't trust the firmware about the length of the wowlan packet.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: add a check on the tid coming from the firmware ba_notif->tid is a firmware-controlled u8 that is used directly as an array index into tid_data[] without any validation. Add a bounds check against IWL_MAX_TID_COUNT before dereferencing the array.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix out-of-bounds tid_data access in BA notif mvmsta->tid_data was indexed by the TFD loop counter 'i' instead of the actual TID value 'tid'. This writes lq_color into a random tid_data slot unrelated to the BA entry. Since multi-TID blockack is not really in use, 'i' was always 0 and no harm was done. Add a out-of-bound check before accessing the array.

In the Linux kernel, the following vulnerability has been resolved: ksmbd: preserve VFS inherited POSIX ACL mask The VFS initializes a child's POSIX ACL from the parent's default ACL and the requested creation mode. Do not mutate the parent ACL or overwrite the child's VFS-computed access and default ACLs afterwards. This preserves restrictive ACL_MASK entries and prevents SMB object creation from widening effective permissions.

In the Linux kernel, the following vulnerability has been resolved: f2fs: embed f2fs_gc_kthread in f2fs_sb_info Instead of allocating f2fs_gc_kthread dynamically, embed it in f2fs_sb_info. This simplifies lifetime management and prepares for fixing race conditions during teardown. - __sbi_store - remount|shutdown - f2fs_stop_gc_thread - access sbi->gc_thread - sbi->gc_thread = NULL - access sbi->gc_thread->f2fs_gc_task

In the Linux kernel, the following vulnerability has been resolved: drm/pagemap: dma-unmap pages before handling migration errors drm_pagemap_migrate_unmap_pages() relies on the pages array to determine which pages require DMA unmapping. However, drm_pagemap_migration_unlock_put_pages() clears the array as part of its cleanup, leaving drm_pagemap_migrate_unmap_pages() with no valid page information if it is called afterward. Call drm_pagemap_migrate_unmap_pages() before drm_pagemap_migration_unlock_put_pages() s…

In the Linux kernel, the following vulnerability has been resolved: i3c: master: Fix device_register() error path When device_register() fails in i3c_master_register_new_i3c_devs(), put_device() is called to drop the reference taken by device_register(). That drops the last reference, so the device's release callback i3c_device_release() runs and frees the i3c_device. Two problems follow from that: i3c_device_release() does WARN_ON(i3cdev->desc), so it warns because desc->dev->desc still points back at the des…

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix maximum allowed access checks The DACL permission check looks for an ACE matching the current user and falls back to the Everyone ACE. It does not consider an Authenticated Users ACE, even though an authenticated session is a member of that well-known group. As a result, opening a file whose access is granted through S-1-5-11 can incorrectly fail with STATUS_ACCESS_DENIED. Treat an Authenticated Users ACE as a fallback entry alongside…

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: fix HE extended capability length check rtw89_mac_check_he_obss_narrow_bw_ru_iter() reads extended capability byte 10, but rejects only datalen values below 10. Byte 10 requires at least 11 bytes. Require datalen >= 11 before reading data[10].

In the Linux kernel, the following vulnerability has been resolved: greybus: audio: bound the topology section sizes against the fetched size gb_audio_gb_get_topology() fetches a topology blob of a module-supplied size, and gbaudio_tplg_parse_data() then walks it by adding the module-supplied size_dais, size_controls and size_widgets fields to form the control, widget and route section offsets. Those le32 sizes are never checked against the fetched blob, so a module reporting a small topology size but large secti…

In the Linux kernel, the following vulnerability has been resolved: staging: octeon: add missing tasklet_kill in cvm_oct_tx_shutdown The TX cleanup tasklet can be scheduled by the watchdog IRQ handler to execute cvm_oct_tx_do_cleanup. There can be a pending tasklet in the queue which might run after the cvm_oct_remove() frees net_device structures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it iterates cvm_oct_device[] which is an array of netdevice pointers. Add tasklet_kill() after free_irq() to ens…
