AI-suggested
Red Hat has released an official security update to address this vulnerability. Users of Red Hat Enterprise Linux 9.4 Extended Update Support and related variants should apply the NetworkManager update as described in Red Hat advisory RHSA-2025:16411. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation actions are indicated by the vendor.
Description
DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.
