Overview

CVE-2022-50492 is a high-severity vulnerability. It was published on October 4, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/msm: fix use-after-free on probe deferral

The bridge counter was never reset when tearing down the DRM device so

that stale pointers to deallocated structures would be accessed on the

next tear down (e.g. after a second late bind deferral).

Given enough bridges and a few probe deferrals this could currently also

lead to data beyond the bridge array being corrupted.
