CVE-2026-74454

CVE-2026-74454 affects the Linux kernel driv3rs/drm vc4 by correcting how the overflow slot size is written during binner memory handling. The issue arises when vc4_overflow_mem_work() sets BPOA to a 512KB slot but BPOS stores the size of the entire 16MB binner BO, enabling the PTB to write tile ...

CVE-2026-74454 drm/vc4: Supply the overflow slot size in BPOS, not the whole bin BO size

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Supply the overflow slot size in BPOS, not the whole bin BO size vc4overflowmemwork points BPOA at a 512KB slot inside the 16MB binner BO, but writes the size of the whole BO to BPOS. On every binner out-of-memory event...

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: reject firmware sections with oversized data In panthorfwloadsectionentry, the data size to copy is calculated without validating it against the allocated sectionsize: section-data.size = hdr.data.end - hdr.data.star...

CVE-2026-74453

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Zero the tile state data array before each BIN job The binner BO is a single 16MB buffer split into 512KB slots that are handed out to jobs at submission time and recycled as jobs complete, without ever being cleared. Ea...

CVE-2026-74453

CVE-2026-74453 (Linux kernel, drm/vc4) : The issue arises in the VC4 tile binning path where the Tile State Data Array (TSDA) for a job’s tile set is left in the binner’s slot between submissions. A 16 MB binner buffer is split into 512 KB slots; TSDA is at the start of each slot and is used by h...

CVE-2026-74450

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-2026-74449

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...
