About this tag
The mptcp vulnerability tag covers discussions about security flaws in the Multipath TCP (MPTCP) implementation, particularly in the Linux kernel. A key example is CVE-2026-46170, a kernel lifetime-management bug in MPTCP address retransmission cleanup that can mishandle socket references. While not a remote-code-execution risk, such vulnerabilities pose challenges for organizations using Windows alongside Linux systems, as they highlight the need for proactive vulnerability management before full CVE enrichment. The tag focuses on kernel-level networking issues, their impact on enterprise IT environments, and the importance of timely patching.
