CVE-2025-21706

CVE-2025-21706 is a Linux kernel vulnerability in the MPTCP path-manager. The in-kernel path-manager’s netlink set_flags path allowed non-subflow endpoints to receive the fullmesh flag due to a permissive hook, enabling an issue observed by syzbot warnings in net/mptcp/pm_netlink.c. The root caus...
