CVE-2026-63856

A flaw was found in the Linux kernel's AMDGPU Video Core Next VCN 2.0 component. This vulnerability arises because the VCN encoder and decoder rings do not properly support 64-bit user fence writes. An attacker could exploit this by submitting command sequences with 64-bit user fences, leading to...

CVE-2026-63855

A flaw was found in the Linux kernel's AMDGPU Video Core Next VCN driver. The VCN encoder and decoder rings do not support 64-bit user fence writes. A local attacker could exploit this by submitting commands with unsupported 64-bit user fences, which could lead to system instability or a denial o...

CVE-2026-63850

A flaw was found in the Linux kernel's AMDGPU Video Core Next VCN component. The VCN encoder and decoder rings, specifically version 5.0.0, do not correctly support 64-bit user fence writes. This can lead to a denial of service, as the kernel will reject command submissions that attempt to use...
