CVE-2025-62229: Red Hat Enterprise Linux 10

High severity, CVSS 7.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
