Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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. (CVE-2025-62229)

Note that Nessus relies on the presence of the package as reported by the vendor.
