A vulnerability in the Linux kernel's AMD GPU driver (drm/amdgpu/vcn) was resolved, specifically addressing the handling of user fences for VCN v5.0.0 encoder and decoder rings. These rings do not support 64-bit user fence writes, and the fix rejects command submissions with user fences to prevent improper behavior. The vulnerability has a CVSS score of 7.8 and affects numerous Linux kernel versions prior to 7.0.0-28.28 and specific other versions. A patch is available and included in updated Linux kernel packages. Users should update and reboot to apply the fix.
