CVE-2026-31461

Local service interruption via resumed display memory leak

Published Apr 22, 2026 · Updated Apr 22, 2026

Memory leak in Linux Kernel 6.13 through 6.18.20 and 6.19 through 6.19.10 allows local users to exhaust kernel memory during resume. In amdgpu_dm.c, the resume path overwrites aconnector->drm_edid for a connected display sink without freeing the prior allocation. An affected AMD display stack, a connected sink, local access, and repeated resume cycles are required to consume memory and interrupt service.
