CVE-2026-43195 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
