CVE-2026-63867 mptcp: close TOCTOU race while computing rcv_wnd
In the Linux kernel, the following vulnerability has been resolved: mptcp: close TOCTOU race while computing rcvwnd The MPTCP output path access locklessly the MPTCP-level ackseq in multiple times, using possibly different values for the dataack in the DSS option and to compute the announced rcv...

PT-2026-61184
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A TOCTOU Time-of-Check to Time-of-Use race condition exists in the MPTCP output path. The system accesses the MPTCP-level ack seq locklessly multiple times, which can lead to the use of...
Linux Distros Unpatched Vulnerability : CVE-2026-53183
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - mptcp: allow subflow rcv wnd to shrink In MPTCP connection, the window field in the TCP header refers to the MPTCP-level rcvnxt and it's right edge should not...

CVE-2026-53183
A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. This vulnerability occurs because the TCP stack independently manages the TCP-level receive window, which can lead to an artificial inflation of the MPTCP receive window. A remote attacker could exploit this by sending...

CVE-2026-53183
CVE-2026-53183 affects the Linux kernel MPTCP implementation. The issue allows the TCP subflow receive window to shrink independently of the netns, which can inflate the MPTCP receive window and cause incoming data to exceed the receiver’s rcvbuf, potentially leading to DoS or a system becoming u...
