Description OSIDB Bzimport 2024-10-21 19:05:46 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Check null pointers before using them

[WHAT & HOW]
These pointers are null checked previously in the same function,
indicating they might be null as reported by Coverity. As a result,
they need to be checked when used again.
