CVE-2026-10805: Networkmanager: networkmanager: local privilege escalation via malformed mud urls in dhclient backend

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.

Potential ATT&CK relevance

Conservative CVE-to-ATT&CK context

These mappings and lookup hints may be relevant to the vulnerability behavior, CWE, affected product, or exposure path. Glexia-inferred context is not an official MITRE, ATT&CK, CWE, or CVE Program mapping.

ATT&CK lookup starting points

Use these exact CWE pages and searches to review the Glexia ATT&CK library from this CVE's weakness and description context.

cwe · medium confidence lookup

CWE-78: Command execution behavior lookup

Command injection weaknesses can lead defenders to review execution techniques and command interpreter telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.

Privilege behavior lookup

The CVE wording references privilege impact, so privilege escalation and authorization behavior review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.

Container behavior lookup

The affected technology mentions containers, so container-specific ATT&CK technique review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
