CVE-2026-80585
A flaw was found in the Linux kernel. In the Multipath TCP MPTCP Fast Open feature, a vulnerability exists where the system incorrectly marks a subflow as MPTFO even when a TCP Fast Open TFO SYN packet does not contain data. This can lead to a stale MPTFO state, potentially triggering a...
EUVD-2026-66502
In the Linux kernel, the following vulnerability has been resolved: mptcp: avoid combining some incoming suboptions Some MPTCP suboptions are mutually exclusive according to the RFC8684, but also because in different places, the code doesn't expect some combinations to be present. That's speciall...
EUVD-2026-66500
In the Linux kernel, the following vulnerability has been resolved: mptcp: fastopen: only mark MPTFO subflows with SYN data Passive TCP Fast Open accepts a valid-cookie SYN even when it carries no data. In that case the child socket's receive queue is intentionally left empty...
EUVD-2026-66503
In the Linux kernel, the following vulnerability has been resolved: mptcp: reclaim forward-allocated memory on RX path errors After commit 9db5b3cec4ec "mptcp: borrow forward memory from subflow", errors in the receive path prior to queueing skbs into the receive queue do not trigger...
EUVD-2026-66501
In the Linux kernel, the following vulnerability has been resolved: mptcp: options: reset DSS fields in case of unexpected size A remote peer could send a malformed DSS with a wrong size, followed by another DSS or MPC + Data. In this case, the first suboption will be ignored, but leaving some...

CVE-2026-80587
CVE-2026-80587 affects the Linux kernel MPTCP subsystem . The vulnerability arises because the kernel failed to enforce mutual-exclusion rules on incoming MPTCP suboptions, while the same restrictions were already applied on the outgoing side via mptcp_write_options. Per RFC 8684, certain subopti...

CVE-2026-80588
CVE-2026-80588 affects the Linux kernel's MPTCP (Multipath TCP) subsystem . After commit 9db5b3cec4ec ("mptcp: borrow forward memory from subflow"), errors in the receive path prior to queueing SKBs into the receive queue fail to trigger reclamation of forward-allocated memory. In pathological dr...
CVE-2026-80586
CVE-2026-80586 affects the Linux kernel MPTCP (Multipath TCP) options handling. A remote peer can send a malformed DSS (Data Sequence Number) suboption with an incorrect size , followed by another DSS or MPC + Data. The first suboption is ignored, but some fields remain written , leading to incon...

CVE-2026-80585
This vulnerability affects the Linux kernel's MPTCP (Multipath TCP) Fast Open implementation. The function mptcp_fastopen_subflow_synack_set_params() incorrectly set the is_mptfo flag before verifying that SYN data had actually been queued on the child socket's receive queue. Data-less TFO SYNs (...
