CVE-2026-43195 Details
Description
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.
A vulnerability in the Linux kernel's AMDGPU driver has been addressed, focusing on the validation of user queue sizes to ensure they comply with hardware requirements. The vulnerability could lead to GPU faults or unexpected behavior. The issue was resolved by adding checks to ensure that queue sizes are a power of two, allowing for efficient ring buffer management, and are no smaller than the AMDGPU_GPU_PAGE_SIZE, preventing inadequate memory allocations.
Users can update to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the official Linux kernel website.
