  - 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)
