In the Linux kernel, the following vulnerability has been resolved:
drm/mxsfb: Disable overlay plane in mxsfbplaneoverlayatomicdisable()
When disabling overlay plane in mxsfbplaneoverlayatomicupdate(), 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 mxsfbplaneoverlayatomicdisable() instead.
