Описание
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.
Отчет
The xorg-x11-server-Xwayland package as shipped by Red Hat Enterprise Linux 8 and 9 is not affected by this issue as Xwayland does not support multiple protocol screens and is not affected by this vulnerability.
