In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: backend: fix error pointer dereference The function drmatomicgetplanestate can return an error pointer and is not checked for it. Add error pointer check. Detected by Smatch: drivers/gpu/drm/sun4i/sun4ibackend.c:496...

CVE-2026-53066

CVE-2026-53066 affects the Linux kernel DRM sun4i backend. The flaw is that drm_atomic_get_plane_state() may return an error pointer which is not checked in sun4i_backend_atomic_check(), allowing a dereference of ERR_PTR() and potential kernel instability. Public details cite a fix in the kernel ...
