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.
