- Summary
- drm/amd/display: Add null check in resource_log_pipe_topology_update
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check in resourcelogpipetopologyupdate
[WHY] When switching from "Extend" to "Second Display Only" we sometimes call resourcegetotgmasterfor_stream on a stream for the eDP, which is disconnected. This leads to a null pointer dereference.
[HOW] Added a null check in dcresource.c/resourcelogpipetopology_update.
