Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw in the drm/amdgpu component allows for invalid user queue size configurations. The system fails to validate that queue sizes are a power of two for efficient ring buffer wrapping and that they meet the minimum AMDGPU GPU PAGE SIZE to prevent undersized allocations. This lack of validation can lead to GPU faults or unexpected behavior by allowing userland to provide invalid configurations to the privileged scheduler.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
