Synopsis

The remote CentOS host is missing a security update for NetworkManager.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the NetworkManager-1.54.4-2.el9 build changelog.

 - A flaw was found in NetworkManager. This local privilege escalation vulnerability exists in NetworkManager's dhclient backend when processing malformed Manufacturer Usage Description (MUD) URLs. A local user can exploit this flaw to escalate privileges by triggering a script via a crafted MUD URL, provided an administrator has explicitly configured NetworkManager to use dhclient. This issue does not affect default configurations of NetworkManager. (CVE-2026-10805)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
