Summary
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.
