In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: handle amdgpucgscreatedevice() errors in amdpowerplay_create()
Add error handling to propagate amdgpucgscreatedevice() failures to the caller. When amdgpucgscreatedevice() fails, release hwmgr and return -ENOMEM to prevent null pointer dereference.
