**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue occurs when switching from "Extend" to "Second Display Only" in the Linux kernel, specifically in the drm/amd/display component. This sometimes leads to calling `resource get otg master for stream` on a stream for the eDP, which is disconnected, resulting in a null pointer dereference. A null check has been added in `dc resource.c/resource log pipe topology update` to resolve this issue. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
