Description SMASH SMASH 2024-02-26 08:58:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix NULL pointer dereference at hibernate

During hibernate sequence the source context might not have a clk_mgr.
So don't use it to look for DML2 support.

Comment 1 Thomas Leroy 2024-02-26 08:58:30 UTC 
Buggy commit is only on stable, which already has the fix, just a changelog
update is left to do
Comment 3 Thomas Zimmermann 2024-03-14 11:56:46 UTC 
The stable branches has moved on to v6.8, which contains the fix. Slowroll is at v6.6, which doesn't need the fix.

There's nothing to do here for me. Unassigning myself.

All done, closing.
