NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64kb package and not the kernel-64kb package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: fix possible UAF in amdgpu_cs_pass1()

Since the gang_size check is outside of chunk parsing loop, we need to reset i before we free the chunk data.
