Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.53/6.5.3 and classified as critical. This issue affects the function mxsfb_plane_overlay_atomic_disable. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/mxsfb: Disable overlay plane in mxsfb_plane_overlay_atomic_disable() When disabling overlay plane in mxsfb_plane_overlay_atomic_update(), overlay plane's framebuffer pointer is NULL. So, dereferencing it would cause a kernel Oops(NULL pointer dereferencing). Fix the issue by disabling overlay plane in mxsfb_plane_overlay_atomic_disable() instead.

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2023-53864 since 12/09/2025. Technical details of the vulnerability are known, but there is no available exploit.
