AI-suggested
A fix has been implemented in the Linux kernel drm/msm driver to address this issue. Users should apply the official kernel updates that include this patch. Since this is a kernel-level fix, upgrading to a patched kernel version is the recommended remediation.
Description
A medium severity vulnerability (CVE-2026-100077) in the Linux kernel's drm/msm driver was resolved. The issue involved unsafe retiring of hung GPU submits before recovery, which could cause GPU page faults due to premature buffer object (BO) freeing. The fix ensures submits are retired only after GPU recovery completes.
