In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: disallow multiple FENCE chunks in one submit amdgpucspass1 dispatches on chunkid once per chunk without rejecting repeated ids. p-ufbo is a single-slot field, so a submission carrying two AMDGPUCHUNKIDFENCE chunks run...

CVE-2026-80582

CVE-2026-80582 affects the Linux kernel 's drm/shmem_helper component. The root cause is that the ->huge_fault handler fails to verify whether a PMD (Page Middle Directory) huge page mapping exceeds the boundaries of the VMA (Virtual Memory Area) before installing it. If the mapping does excee...

CVE-2026-80582 drm/shmem_helper: Check VMA boundaries for PMD mappings

In the Linux kernel, the following vulnerability has been resolved: drm/shmemhelper: Check VMA boundaries for PMD mappings In the -hugefault handler do not install a PMD huge page mapping if the huge page exceeds the boundaries of the VMA. All other -hugefault handlers have similar checks and the...

CVE-2026-80577

This vulnerability affects the Linux kernel DRM Panthor driver (Arm Mali GPU subsystem). The root cause is in panthor_fw_load_section_entry(): when a firmware section has an empty VA range , BO (Buffer Object) creation is skipped, leaving section->mem as NULL . Subsequent reload and unplug pat...

CVE-2026-80577 drm/panthor: skip zero-sized firmware sections

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: skip zero-sized firmware sections panthorfwloadsectionentry skips BO creation when the firmware section VA range is empty. If such a section is added to the firmware section list, section-mem is left as NULL. Later...

CVE-2026-80576 drm/amdgpu: reject oversized IBs with per-ring packet limits

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject oversized IBs with per-ring packet limits On GFX rings, amdgpucsp2ib passed user-supplied ibbytes through to ib-lengthdw without a limit, while ringemitib encodes length into packet fields. Oversized values can...

CVE-2026-80576

CVE-2026-80576 affects the Linux kernel's drm/amdgpu driver. In amdgpu_cs_p2_ib(), a user-supplied ib_bytes value was passed to ib->length_dw without a limit. Since ring_emit_ib() encodes this length into packet fields, oversized values can corrupt adjacent control bits , destabilizing command...

CVE-2026-80542

CVE-2026-80542 is a NULL pointer dereference in the Linux kernel's AMD GPU display driver (drm/amd/amdgpu). The vulnerable function amdgpu_dm_crtc_set_vblank() dereferences acrtc_state->stream before a stream is attached to the CRTC, causing a kernel crash at address 0x8 when vblank is enabled...

CVE-2026-80541

A vulnerability in the Linux kernel's drm/amdgpu driver allows a local, low-privileged user to trigger a kernel BUG_ON() crash by crafting a GEM_CREATE ioctl with an invalid combination of domain flags (e.g., CPU|GTT|VRAM combined with DOORBELL, GDS, GWS, or OA). The root cause is that while indi...

CVE-2026-80539 drm/amdgpu: disallow multiple FENCE chunks in one submit

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: disallow multiple FENCE chunks in one submit amdgpucspass1 dispatches on chunkid once per chunk without rejecting repeated ids. p-ufbo is a single-slot field, so a submission carrying two AMDGPUCHUNKIDFENCE chunks run...

CVE-2026-80540 drm/amdgpu: Fix UVD decode image min size calculation

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix UVD decode image min size calculation This needs to use pitch instead of width. Also reject pitch over 4096 to avoid overflow. cherry picked from commit b41c8cb12e202b220353332ab87dc01a11f69304...

CVE-2026-80539

CVE-2026-80539 affects the Linux kernel 's drm/amdgpu driver. In amdgpu_cs_pass1(), a user submission carrying multiple AMDGPU_CHUNK_ID_FENCE chunks causes amdgpu_cs_p1_user_fence() to run more than once. Because p->uf_bo is a single-slot field, each subsequent call overwrites it with a newly ...
