The vulnerability of the mptcp_established_options_dss() function in the net/mptcp/options.c module of the MPTCP protocol implementation in the Linux operating system allows a attacker to cause a service failure.
The vulnerability of the mptcpestablishedoptionsdss function in the net/mptcp/options.c module of the MPTCP protocol implementation in the Linux operating system is related to incorrect calculation of buffer size when processing received packets. Exploiting this vulnerability can allow a remote...
Unity Linux 20.1070e Security Update: kernel (UTSA-2025-001503)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-001503 advisory. In the Linux kernel, the following vulnerability has been resolved: tcp: fix mptcp DSS corruption due to large pmtu xmit Syzkaller was able to trigger a DSS...
SUSE CVE-2026-80586
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...
The vulnerability in the `net/mptcp/pm_kernel.c` component of the Linux operating system allows a hacker to cause a service failure.
The vulnerability of the net/mptcp/pmkernel.c component in the Linux operating system is related to insufficient blocking mechanisms. Exploiting this vulnerability could allow an attacker to cause a service failure...
CVE-2026-80588
A flaw was found in the Linux kernel's Multipath TCP mptcp implementation. Errors occurring during the receive path, before data is queued, may prevent the system from reclaiming forward-allocated memory. This can lead to an unbounded increase in memory usage under certain network conditions, suc...
CVE-2026-80587
A flaw was found in the Multipath TCP MPTCP implementation within the Linux kernel. This vulnerability arises from the kernel's handling of mutually exclusive MPTCP suboptions. A remote attacker could send specially crafted MPTCP suboptions that, when combined, are not expected by the kernel. Thi...
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...

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...
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...
