AI-suggested
Red Hat advises ensuring that NetworkManager is not configured to use the dhclient backend. The default configuration does not enable dhclient. If a custom configuration file such as /etc/NetworkManager/conf.d/00-dhcp.conf contains the line '[main] dhcp=dhclient', this line should be removed or commented out. After making this change, restart the NetworkManager service using 'sudo systemctl restart NetworkManager'. Note that restarting NetworkManager will temporarily disrupt network connectivity.
Description
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.
