CVE-2026-89813: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: force complete the KIQ ring fences on reset Like the MES scheduler ring, the KIQ ring sets noscheduler = true and uses a polling fence, so it is skipped by the force-completion loop in amdgpudevicepreasicreset. Its hw...

CVE-2026-80919

A flaw was found in the Linux kernel's drm/amdgpu component. A local attacker could trigger a hung job, causing the amdgpudevcoredumpformat function to recursively acquire a lock. This recursive locking can lead to a self-deadlock, resulting in a Denial of Service DoS where the system becomes...

kernel: drm/amdgpu: Fix fence put before wait in amdgpu_amdkfd_submit_ib

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. An issue in the amdgpuamdkfdsubmitib function allows a local user to trigger a use-after-free vulnerability. This occurs because a fence reference is incorrectly released before waiting for job completion, potentially freeing the memor...

kernel: drm/amdgpu: Fix use-after-free race in VM acquire

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. This vulnerability involves a timing issue, known as a race condition, during the process of acquiring a Virtual Machine VM. When multiple processes attempt to access the same VM simultaneously, a local attacker could exploit this flaw...
