CVE-2024-3661
DHCP routing options can manipulate interface-based VPN traffic
Description
DHCP can add routes to a client’s routing table via the classless static route option (121).

An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.
