CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's AMD GPU (amdgpu) driver, specifically the Video Codec Network (VCN) encoder and decoder rings, which improperly handle 64-bit user fence writes. This flaw can lead to denial of service by rejecting command submissions that utilize user fences, potentially impacting system stability and performance. Organizations utilizing Linux systems with AMD GPUs should prioritize patching to mitigate the risk of exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn: set no_user_fence for VCN v2.5 enc/dec rings VCN encoder and decoder rings do not support 64-bit user fence writes, reject CS submissions with user fences.
