CVE-2026-53066

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An error pointer dereference exists in the drm/sun4i backend. The function drm atomic get plane state() can return an error pointer that is not properly checked before use. This can lead to a system crash when the sun4i backend atomic check() function dereferences the plane state variable while it contains an ERR PTR(), which is a special pointer value used by the kernel to indicate an error.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
