edid leak

The edid leak tag covers a specific memory leak vulnerability in the Linux AMDGPU DRM subsystem, tracked as CVE-2026-31461. This issue occurs in the amdgpu_dm display driver where the drm_edid pointer is overwritten without freeing the previous allocation during reconnect or resume events, slowly leaking memory over time. The fix involves freeing the old EDID object before assigning a new one. The CVE is being addressed through the Linux stable pipeline and Microsoft's Security Update Guide. This tag is relevant for users running Linux with AMD graphics hardware who want to understand the security implications and update requirements for this narrowly scoped memory leak.
