CVE-2026-43400

CVE-2026-43400 affects the Linux kernel’s DRM/AMDGPU component. The vulnerability arises from missing upper-bound input validation in the amdgpu_userq_signal_ioctl handler, allowing huge input values to trigger an Out-Of-Memory (OOM) condition and thus a Denial of Service. The issue is mitigated ...

CVE-2026-43399

CVE-2026-43399 affects the Linux kernel amdgpu driver: a reference leak in amdgpu_userq_wait_ioctl occurs when an ioctl is aborted because the output array is too small. The fix drops references to syncobj and timeline fence during abort, and is cherry-picked from commit 68951e9c3e6bb22396bc42ef2...
