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

drm/amd/display: Fix hang/underflow when transitioning to ODM4:1

[Why]
Under some circumstances, disabling an OPTC and attempting to reclaim
its OPP(s) for a different OPTC could cause a hang/underflow due to OPPs
not being properly disconnected from the disabled OPTC.

[How]
Ensure that all OPPs are unassigned from an OPTC when it gets disabled.
