CVE-2026-63850

The CVE-2026-63850 vulnerability affects the Linux kernel’s DRM/AMDGPU VCN path. Specifically, the VCN encoder/decoder rings in certain AMDGPU environments do not support 64-bit user fence writes, and are now prevented from submitting CS with user fences. The issue arises in VCN v5.0.0 enc ring b...
