Description OSIDB Bzimport 2025-07-03 09:04:04 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Don't treat wb connector as physical in create_validate_stream_for_sink

Don't try to operate on a drm_wb_connector as an amdgpu_dm_connector.
While dereferencing aconnector->base will "work" it's wrong and
might lead to unknown bad things. Just... don't.
