In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: backend: fix error pointer dereference The function drm_atomic_get_plane_state() can return an error pointer and is not checked for it.
Does this matter?
Lower severity and a low EPSS score (0.11%). Track it; it rarely justifies an emergency change on its own.
