No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
