Description OSIDB Bzimport 2025-12-24 14:04:07 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dpu: Add check for cstate

As kzalloc may fail and return NULL pointer,
it should be better to check cstate
in order to avoid the NULL pointer dereference
in __drm_atomic_helper_crtc_reset.
