CVE-2026-93139 drm/amdgpu/mes: Fix hung_queue_db_array loop limit for multi-XCC

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/mes: Fix hungqueuedbarray loop limit for multi-XCC The loop iterated only AMDGPUMAXMESPIPES times, leaving entries uninitialized for multi-XCC GPUs. This causes null pointer dereferences when accessing arrays indexed b...

CVE-2026-93139

CVE-2026-93139 affects the Linux kernel's amdgpu driver , specifically the MES (Micro-Engine Scheduler) component. The root cause is a loop in the hung_queue_db_array that iterated only AMDGPU_MAX_MES_PIPES times, leaving entries uninitialized for multi-XCC GPUs. This results in null pointer dere...

CVE-2026-90286

CVE-2026-90286 is a Linux kernel vulnerability in the DRM/AMDGPU GFX6 driver. On GFX6 GPUs, compute rings share the same Command Processor (CP) path as the graphics ring, but the Packet Front-End (PFP) was not being correctly used on compute queues. The fix ensures PFP is used for register writes...
