CVE-2026-80890: Linux kernel may accept expired SCTP connection cookies
CVE-2026-80890 · published 2 months ago
Summary
The Linux kernel's SCTP networking code could mistakenly accept a connection request that is older than the allowed time limit. This can let an attacker replay a stale cookie and re‑establish a network session after it should have expired. Updating the kernel to the latest version fixes the check, so apply the current Linux updates as soon as possible.

BELL-CVE-2026-80890
In the Linux kernel, the following vulnerability has been resolved: sctp: reject stale cookies with mismatched verification tags sctp_unpack_cookie() skips cookie expiration checks whenever an association already exists. This is broader than the exception in RFC 9260 Section 5.2.4. For an existing association, Section 5.2.4 permits an expired State Cookie only when both Verification Tags in the cookie match the current association. Otherwise, the packet SHOULD be discarded and a Stale Cookie ERROR MUST be sent. The broad check lets an expired Action A restart cookie reach sctp_sf_do_dupcook_a(). In a runtime test with the default 60 second cookie lifetime, replaying such a cookie after 65 seconds returned a COOKIE-ACK and restarted the association. Check cookie expiration unless both Verification Tags match. This preserves the Action D exception for a lost COOKIE ACK while rejecting expired cookies in all other cases.
