Description
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.

Executive Summary

This vulnerability occurs in the Linux kernel's mxsfb driver where the overlay plane's framebuffer pointer is NULL when disabling the overlay plane in the function mxsfb_plane_overlay_atomic_update(). Dereferencing this NULL pointer causes a kernel Oops (a type of kernel crash). The fix involves disabling the overlay plane in a different function, mxsfb_plane_overlay_atomic_disable(), to avoid the NULL pointer dereference.

Impact Analysis

This vulnerability can cause the Linux kernel to crash (kernel Oops) due to a NULL pointer dereference in the mxsfb overlay plane handling. Such crashes can lead to system instability, potential denial of service, and disruption of normal operations on affected systems.
