Description OSIDB Bzimport 2025-02-26 03:19:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Call dc_stream_release for remove link enc assignment

[Why]
A porting error resulted in the stream assignment for the link
being retained without being released - a memory leak.

[How]
Fix the porting error by adding back the dc_stream_release() intended
as part of the original patch.
