Description OSIDB Bzimport 2026-05-06 13:07:41 UTC
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.
