Description OSIDB Bzimport 2025-12-16 14:03:15 UTC
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Cache streams targeting link when performing LT automation

[WHY]
Last LT automation update can cause crash by referencing current_state and
calling into dc_update_planes_and_stream which may clobber current_state.

[HOW]
Cache relevant stream pointers and iterate through them instead of relying
on the current_state.
