Networkmanager: networkmanager: 802-1x ca-path and phase2-ca-path bypass private_user restriction, allowing wpa-enterprise server validation bypass (incomplete fix for cve-2025-9615)
NetworkManager did not apply the private_user restriction to the 802-1x.ca-path and phase2-ca-path directory-valued connection properties. This incomplete fix for CVE-2025-9615 allows an unprivileged local user to point a private WPA-Enterprise (802.1X) connection profile's CA path at an attacker-controlled directory, bypassing server certificate validation and enabling credential theft via a rogue access point.
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.
A flaw was found in NetworkManager. The NetworkManager package allows access to files that may belong to other users. NetworkManager allows non-root users to configure the system's network. The daemon runs with root privileges and can access files owned by users different from the one who added the connection.
A flaw was found in NetworkManager. When a system running NetworkManager with DEBUG logs enabled and an interface eth1 configured with LLDP enabled, a malicious user could inject a malformed LLDP packet. NetworkManager would crash, leading to a denial of service.
A flaw was found in NetworkManager in versions before 1.30.0. Setting match.path and activating a profile crashes NetworkManager. The highest threat from this vulnerability is to system availability.
It was found that nmcli, a command line interface to NetworkManager did not honour 802-1x.ca-path and 802-1x.phase2-ca-path settings, when creating a new profile. When a user connects to a network using this profile, the authentication does not happen and the connection is made insecurely.
Out-of-Bounds write in systemd-networkd dhcpv6 option handling
A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239.
GNOME NetworkManager version 1.10.2 and earlier contains a Information Exposure (CWE-200) vulnerability in DNS resolver that can result in Private DNS queries leaked to local network's DNS servers, while on VPN. This vulnerability appears to have been fixed in Some Ubuntu 16.04 packages were fixed, but later updates removed the fix. cf. https://bugs.launchpad.net/ubuntu/+bug/1754671 an upstream fix does not appear to be available at this time.
Race condition in Network Manager before 1.0.12 as packaged in Red Hat Enterprise Linux Desktop 7, Red Hat Enterprise Linux HPC Node 7, Red Hat Enterprise Linux Server 7, and Red Hat Enterprise Linux Workstation 7 allows local users to obtain sensitive connection information by reading temporary files during ifcfg and keyfile changes.
GNOME NetworkManager allows remote attackers to cause a denial of service (IPv6 traffic disruption) via a crafted MTU value in an IPv6 Router Advertisement (RA) message, a different vulnerability than CVE-2015-8215.
The receive_ra function in rdisc/nm-lndp-rdisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in NetworkManager 1.x allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message, a similar issue to CVE-2015-2922.
GNOME NetworkManager before 0.8.6 does not properly enforce the auth_admin element in PolicyKit, which allows local users to bypass intended wireless network sharing restrictions via unspecified vectors.
nm-applet.conf in GNOME NetworkManager before 0.7.0.99 contains an incorrect deny setting, which allows local users to discover (1) network connection passwords and (2) pre-shared keys via calls to the GetSecrets method in the dbus request handler.
