DescriptionNVD

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.

Patchwork: https://patchwork.freedesktop.org/patch/502665/

Technical ContextAI

A use-after-free vulnerability occurs when a program continues to use a pointer after the referenced memory has been freed, leading to undefined behavior. This vulnerability is classified as Use After Free (CWE-416).

RemediationAI

A vendor patch is available — apply it immediately. Use memory-safe languages. Implement proper object lifecycle management. Use static and dynamic analysis tools to detect UAF patterns.
