Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-11 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: validate user queue size constraints

Add validation to ensure user queue sizes meet hardware requirements: - Size must be a power of two for efficient ring buffer wrapping - Size must be at least AMDGPU_GPU_PAGE_SIZE to prevent undersized allocations

This prevents invalid configurations that could lead to GPU faults or unexpected behavior.

Severity ?

5.5 (Medium)
