CVE-2025-62229

A flaw was found in the X.Org X server and Xwayland when processing X11 Present extension notifications. Improper error handling during notification creation can leave dangling pointers that lead to a use-after-free condition. This can cause memory corruption or a crash, potentially allowing an attacker to execute arbitrary code or cause a denial of service.

The Red Hat Product Security team has rated this vulnerability as Moderate. The flaw is a use-after-free in X11 Present notification handling that could lead to integrity and availability impacts if exploited. Moreover, the X.Org server does not run with root privileges in Red Hat Enterprise Linux 8 and 9, limiting the potential impact and preventing system-wide compromise.
