CVE-2026-43169

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

Description An issue exists in the drm/buddy component where requested allocation sizes are rounded up using roundup pow of two() when DRM BUDDY CONTIGUOUS ALLOCATION is set, or aligned via round up() for non-contiguous allocations with a large min block size. These operations can result in a rounded size that exceeds mm->size, subsequently triggering a BUG ON() failure when the calculated order exceeds mm->max order.

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