CVE-2026-31461 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix drm_edid leak in amdgpu_dm [WHAT] When a sink is connected, aconnector->drm_edid was overwritten without freeing the previous allocation, causing a memory leak on resume. [HOW] Free the previous drm_edid before updating it. (cherry picked from commit 52024a94e7111366141cfc5d888b2ef011f879e5)
A memory leak vulnerability has been identified in the Linux kernel's AMD graphics driver, specifically within the display management component of the AMD GPU driver. This issue arises when a sink is connected; the connector's EDID (Extended Display Identification Data) is overwritten without freeing the previously allocated memory. This oversight leads to a memory leak when the system resumes from a suspended state. The vulnerability affects several versions of the Linux kernel.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
