Description OSIDB Bzimport 2024-07-29 15:42:57 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport

[Why]
Potential out of bounds access in dml2_calculate_rq_and_dlg_params()
because the value of out_lowest_state_idx used as an index for FCLKChangeSupport
array can be greater than 1.

[How]
Currently dml2 core specifies identical values for all FCLKChangeSupport
elements. Always use index 0 in the condition to avoid out of bounds access.
