| CVE-2026-99000 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix shrinker accounting double-subtraction on nested external pins xe_bo_pin_external() and xe_bo_unpin_external() support nested pins, since the underlying ttm_bo_pin()/ttm_bo_unpin() maintain a pin_count refcount rather than a boolean. However, the shrinker accounting calls xe_ttm_tt_account_subtract() and xe_ttm_tt_account_add() are invoked unconditionally on every pin_external()/unpin_external() call, instead of only on the transition into and out of the pinned state. An external BO (dma-buf) can be pinned more than once while already pinned, for example when it has multiple attachments/importers, each independently calling xe_bo_pin_external(). Each such nested pin subtracts the BO's pages from the shrinker's accounting again, even though the BO's pages were already removed from consideration by the first pin. Symmetrically, each nested unpin adds them back again before the BO is actually unpinned. This desynchronizes the shrinker's page and object counts from reality, and since they are declared as signed long but interpreted as unsigned long in xe_shrinker_count(), the underflow can turn into an enormous shrinkable/purgeable page count, causing the shrinker to be invoked excessively under memory pressure. Guard the accounting calls with the same pin-count transition checks already used to guard the pinned_link list maintenance, so accounting is only updated on the outermost pin and the final unpin. While centralizing this logic into xe_bo_account_pin()/ xe_bo_account_unpin(), also close a second, related accounting gap affecting imported dma-bufs. For an imported bo's ttm_tt, xe's ttm_tt_populate hook (xe_ttm_tt_populate()) early-returns without calling xe_ttm_tt_account_add(), since TTM_TT_FLAG_EXTERNAL is set without TTM_TT_FLAG_EXTERNAL_MAPPABLE. However, TTM core's ttm_tt_populate() wrapper unconditionally marks the tt as populated on driver-hook success, so ttm_tt_is_populated() still reports true for it. xe_bo_account_pin()/xe_bo_account_unpin() trusted ttm_tt_is_populated() as a proxy for "these pages are accounted for by the shrinker", and would subtract/add pages for such a tt that were never added in the first place, again underflowing the shrinker's counts. This is reachable today via xe_bo_pin_external(), and would have become newly reachable via the fb-pin path once this patch routes __xe_pin_fb_vma() through xe_bo_pin_account() below, so fix it here rather than in a later patch, to avoid a commit in this series that introduces the regression before fixing it. Skip the accounting for imported bos, using the same EXTERNAL && !EXTERNAL_MAPPABLE test xe_ttm_tt_populate()/xe_ttm_tt_unpopulate() use to decide whether to act, via a new xe_ttm_bo_is_imported() helper (hoisted up from its only prior use site). v2: - Fix the critical issue caught by Sashiko AI review: the pin-count transition check introduced here was still bypassed by the fb-pin path (__xe_pin_fb_vma()/__xe_unpin_fb_vma()), which could leave a stale pinned_link entry and a permanent shrinker accounting leak when the fb-unpin performed the true last unpin. Addressed in a separate follow-up patch in this series rather than folded in here, since it is a distinct bug with its own Fixes: tag. - Drop the unneeded local "last_unpin" variable in xe_bo_unpin_external(), restoring the original inline bo->ttm.pin_count == 1 check; it was a no-op rename not used by any of the new accounting helpers, and was going to be deleted again by the follow-up patch anyway. v3: - Exclude imported dma-bufs from the pin/unpin shrinker accounting, fixing another underflow caught by Sashiko AI review. - Add a short comment on the backup-object pin site noting it's already populated/accounted at pin time, addressing (as a false-positive clarification, no code fix needed) a separate Medium-severity accounting-leak concern also caught by Sashiko AI ---truncated--- | ||||
| CVE-2026-109219 | 2026-10-23 | 9.8 Critical | ||
| The Mang Board plugin for WordPress is vulnerable to Arbitrary File Upload in version 2.4.4 via the mbw_file_upload function. This is due to missing file extension validation on the attacker-supplied image_path parameter, whose basename-derived file name bypasses the extension allowlist applied only to the separate file_name parameter. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. Exploitation requires the board to be configured to allow guest posts, which is the plugin's default mode; the required nonce is printed on every public board page, making it readable by any unauthenticated visitor without a WordPress login. | ||||

| CVE-2026-98778 | 1 Linux | 1 Linux Kernel | 2026-10-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: binder: fix is_failure flag for superseded transaction cleanup When a TF_UPDATE_TXN transaction supersedes a pending async transaction, binder_release_entire_buffer() is called with is_failure=false. Since the superseded transaction was never delivered, binder_apply_fd_fixups() was never called and no fds were installed in the target process. With is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets stale buffer contents as installed fd numbers and passes them to binder_deferred_fd_close(), closing unrelated file descriptors. Pass is_failure=true since the transaction was never delivered to the target, matching the semantics of all other undelivered-transaction cleanup paths. | ||||
| CVE-2026-98779 | 1 Linux | 1 Linux Kernel | 2026-10-23 | 1.9 Low |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix ACP MFD device leak on init failure acp_hw_init() registers ACP child devices with mfd_add_devices() before attaching them to the ACP power domain and initializing the hardware. If attaching a child to the power domain fails, or if the ACP reset or clock enable operation times out, the failure path frees only the source cell, resource, and platform-data allocations. The child platform devices already registered by mfd_add_devices() remain registered and are never released. Remove the children from the power domain and unregister the MFD devices on failures that occur after mfd_add_devices() succeeds. Keep mfd_add_devices() failures on the existing cleanup path since the MFD core already rolls back partially registered children itself. The issue was identified by a static analysis tool I developed and confirmed by manual review. (cherry picked from commit 63da68d6a2279ec945581c990c5a59a5ae8b5560) | ||||
| CVE-2026-98780 | 1 Linux | 1 Linux Kernel | 2026-10-23 | 1.9 Low |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix IP instance memory leak on kobject add failure amdgpu_discovery_sysfs_ips() allocates ip_hw_instance with kzalloc_flex() and initializes its embedded kobject before calling kobject_add(). If kobject_add() fails, the return value is ignored and execution continues without dropping the initial kobject reference. The failed kobject is not retained in the kset list, so the normal sysfs teardown path cannot find it. As a result, ip_hw_instance_release() is never called and the ip_hw_instance allocation is leaked. Call kobject_put() when kobject_add() fails so the initial reference is dropped and ip_hw_instance_release() can free the allocation. Keep the existing best-effort sysfs behavior by continuing with the remaining IP entries after the failed registration. The issue was identified by a static analysis tool I developed and confirmed by manual review. (cherry picked from commit 5c75fbcca8af1096d8d9415b91d8ea6212c22ee1) | ||||

| CVE-2026-98884 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mmc: core: Add validation for host-provided max_segs The max_segs field is of type unsigned short, and if a host driver sets an excessively large value, it may be truncated to zero. This can cause mmc_alloc_sg() to call kmalloc_objs() with a zero size allocation request, which leads to undefined behavior. Under the SLUB allocator, kmalloc(0) returns a special pointer (ZERO_SIZE_PTR). The subsequent 'if (sg)' check will evaluate to true, and sg_init_table() will then attempt to access invalid memory, resulting in a crash: dwmmc_rockchip 2a310000.mmc: Successfully tuned phase to 133 mmc1: new UHS-I speed SDR104 SDHC card at address aaaa Unable to handle kernel paging request at virtual address 0000001ffffffff0 Mem abort info: ESR = 0x0000000096000004 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x04: level 0 translation fault Data abort info: ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 CM = 0, WnR = 0, TnD = 0, TagAccess = 0 GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=0000000102c88000 [0000001ffffffff0] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 0000000096000004 [#1] SMP Modules linked in: CPU: 2 UID: 0 PID: 102 Comm: kworker/2:1 Not tainted 7.0.0-rc6-next-20260331-00013-g4d93c25963c5-dirty #80 PREEMPT Hardware name: Rockchip RK3576 EVB V10 Board (DT) Workqueue: events_freezable mmc_rescan pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : sg_init_table+0x2c/0x50 lr : sg_init_table+0x24/0x50 sp : ffff8000837db710 x29: ffff8000837db710 x28: 000000000000c000 x27: 0000000000000300 x26: 0000000000000000 x25: 0000000000000040 x24: ffff0000c46a0000 x23: 0000000000000000 x22: ffff0000c0c73c00 x21: 0000000000000010 x20: 0000000000000010 x19: 0000000000000000 x18: 000000000000002c x17: 0000000000000000 x16: 0000000000000001 x15: 0000000000000000 x14: 0000000000000400 x13: ffff8000837dc000 x12: 0000000000000000 x11: ffff0000c0c73ca0 x10: 0000000000000040 x9 : 459ec1f0abbdbb00 x8 : 0000001fffffffe0 x7 : 0000000000000000 x6 : 000000000000003f x5 : 0000000000035579 x4 : 0000000000000901 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000010 Call trace: sg_init_table+0x2c/0x50 (P) mmc_mq_init_request+0x64/0x90 blk_mq_alloc_map_and_rqs+0x3ac/0x480 blk_mq_alloc_set_map_and_rqs+0x98/0x1e0 blk_mq_alloc_tag_set+0x1c0/0x290 mmc_init_queue+0x120/0x370 mmc_blk_alloc_req+0x150/0x420 To prevent this, add a validation check in mmc_mq_init_request() to detect when sg_len (derived from max_segs) is zero. If sg_len is zero, we return an error and print an error message, allowing host driver developers to identify and fix incorrect max_segs configuration. This is a defensive measure that ensures the MMC core fails gracefully when host drivers provide invalid max_segs values, rather than crashing with a page fault. | ||||
