CVE-2025-21706

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

mptcp: pm: only set fullmesh for subflow endp

With the in-kernel path-manager, it is possible to change the 'fullmesh' flag. The code in mptcp_pm_nl_fullmesh() expects to change it only on 'subflow' endpoints, to recreate more or less subflows using the linked address.

Unfortunately, the set_flags() hook was a bit more permissive, and allowed 'implicit' endpoints to get the 'fullmesh' flag while it is not allowed before.

That's what syzbot found, triggering the following warning:
