CVE-2026-46170

CVE-2026-46170 affects the Linux kernel MPTCP implementation. When ADD_ADDR is retransmitted, the socket reference counting can fail to free the sk, which may trigger indefinite waiting in timer synchronization and cause a DoS. The root cause is improper timer handling during sk_free that could c...

EUVD-2026-32797

In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADDADDR rtx: free sk if last When an ADDADDR is retransmitted, the sk is held in skresettimer, and released at the end. If at that moment, it was the last reference being held, the sk would not be freed. sockput should...

CVE-2026-46158

The CVE-2026-46158 issue is in the Linux kernel MPTCP implementation: when ADD_ADDR is retransmitted, the socket reference count may not be released reliably, creating a potential resource leak. The fix adds a proper exit path to call sock_put (__sock_put) at the end of the handling and removes a...
