CVE-2025-40336

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

Description A flaw exists in the Linux kernel’s drm/gpusvm subsystem related to the hmm pfn to map order() function. The issue arises when the huge memory map (hmm) range partially overlaps a huge page, potentially leading to memory mapping outside the intended range. The fix aligns the code with the xe userptr code, which will directly use gpusvm in a future patch.

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