CVE-2026-74450 drm/amd/pm: fix pptable use-after-free

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix pptable use-after-free amdgpudpmgetpptable returns a pointer to a driver-owned power table after dropping adev-pm.mutex. The sysfs path then copies from that pointer. A concurrent pptable write can replace and fre...

CVE-2026-74451

CVE-2026-74451 affects the Linux kernel DRM panthor path. The root cause is that iface_fw_to_cpu_addr() only verified that the MCU virtual address lies within the shared section, but the returned pointer was used as a full firmware interface structure, allowing out-of-bounds accesses when the add...

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: validate firmware interface structure sizes ifacefwtocpuaddr only checks that the firmware-provided MCU virtual address points inside the shared section. The returned pointer is later used as a full firmware interfac...

CVE-2026-74450

CVE-2026-74450 : In the Linux kernel, the drm/amd/pm path had a use-after-free in amdgpu_dpm_get_pp_table when a concurrent write occurred during a sysfs copy of a driver-owned power table. The root cause was returning a pointer to the driver-owned pptable after dropping the adev->pm.mutex. Th...

CVE-2026-74449 drm/amd/display: Fix divide-by-zero in calculate_mcache_setting on zero viewport

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix divide-by-zero in calculatemcachesetting on zero viewport If a plane reaches calculatemcachesetting with a zero-area viewport, calculatemcachesetting exits early with nummcaches == 0 and mvmpgwidth/height == ...

CVE-2026-74449 drm/amd/display: Fix divide-by-zero in calculate_mcache_setting on zero viewport

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix divide-by-zero in calculatemcachesetting on zero viewport If a plane reaches calculatemcachesetting with a zero-area viewport, calculatemcachesetting exits early with nummcaches == 0 and mvmpgwidth/height == ...

CVE-2026-74449

The CVE-2026-74449 issue affects the Linux kernel DRM/AMD display path. A zero-area viewport can lead calculate_mcache_setting to exit with num_mcaches == 0 and mvmpg_width/height == 0, causing a divide-by-zero panic (and potential num_mcaches underflow). The fix changes calculate_mcache_setting ...

CVE-2026-74448

CVE-2026-74448 affects the Linux kernel’s DRM/amdkfd path. When MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during the first queue creation for a process, pqm_create_queue() may return early via a plain return, skipping the error cleanup and leaving a reserved QID bit set in queue_s...

CVE-2026-74447

In the Linux kernel (drm/amdkfd), a uint32_t overflow in EOP ring buffer size alignment was fixed. The issue occurred because eop_ring_buffer_size (u32) is aligned with PAGE_SIZE in kfd_queue_acquire_buffers() using 32‑bit arithmetic, allowing a user size like 0xFFFFF001 to wrap to 0 and bypass t...
