MEDIUM 4.7EPSS 0.71%

Does this matter?

Lower severity and a low EPSS score (0.71%). Track it; it rarely justifies an emergency change on its own.

Description

A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed.
