CVE-2026-63853

A flaw was found in the Linux kernel's AMD GPU Video Core Next VCN driver. This vulnerability arises because the VCN encoder and decoder rings, responsible for video processing, do not support 64-bit user fence writes. An attacker could exploit this by submitting command requests that include the...

CVE-2026-63846

A flaw was found in the Linux kernel's drm/amdgpu/jpeg component, specifically within the JPEG v3.0 ring. This component does not support 64-bit user fence writes. Consequently, any command submissions CS that attempt to use 64-bit user fences will be rejected, leading to a functional limitation ...

CVE-2026-63847

A flaw was found in the Linux kernel's AMD GPU JPEG driver. This issue occurs because the JPEG hardware component does not properly handle certain types of graphics commands, specifically 64-bit user fence writes. An attacker could craft and submit malicious commands, causing the system to reject...

CVE-2026-63843

A flaw was found in the Linux kernel's AMD GPU Graphics Processing Unit JPEG Joint Photographic Experts Group component. This vulnerability arises because the JPEG v4.0.5 ring does not correctly support 64-bit user fence writes. A local attacker could exploit this by submitting commands with 64-b...

CVE-2026-63840

A flaw was found in the Linux kernel's drm/amdgpu/jpeg driver. The JPEG v5.3.0 ring within this driver does not support 64-bit user fence writes. A local user or application attempting to submit commands with 64-bit user fences to the amdgpu JPEG v5.3.0 ring will have these submissions rejected...

CVE-2026-63852

A flaw was found in the Linux kernel's AMD GPU Graphics Processing Unit Video Core Next VCN component. This vulnerability arises because the VCN encoder and decoder rings do not properly handle 64-bit user fence writes, leading to the rejection of command submissions that utilize these fences. An...

CVE-2026-63851

A flaw was found in the Linux kernel's AMDGPU VCN Video Core Next driver. This issue arises because the VCN hardware's encoder and decoder components do not properly handle 64-bit user fence writes. An attacker could trigger this by submitting specific commands, causing the system to reject these...

CVE-2026-63845

A flaw was found in the Linux kernel, specifically within the AMD GPU's JPEG Joint Photographic Experts Group ring component. This vulnerability occurs because the JPEG v4.0 rings do not support 64-bit user fence writes. This can lead to the system rejecting command submissions that utilize user...
