What is CVE-2026-10805?

A local privilege escalation vulnerability has been identified in NetworkManager, specifically within the dhclient backend. This flaw arises when NetworkManager processes incorrectly formatted Manufacturer Usage Description (MUD) URLs. A local user may exploit this vulnerability to escalate their privileges by crafting a malicious MUD URL that triggers a script. It is important to note that this vulnerability only affects systems where an administrator has specifically configured NetworkManager to use dhclient, leaving default configurations unaffected.
