CVE-2024-50185Network attack vector

Data corruption and service interruption via malformed DSS

Published Nov 8, 2024 · Updated Aug 5, 2026

Improper MPTCP DSS handling in affected Linux 5.7 and later kernels allows remote attackers to corrupt data or interrupt service. The MPTCP receive path treats inconsistent DSS mappings as warning conditions instead of consistently invoking TCP fallback or resetting the subflow. Reachability requires an MPTCP connection and a peer-supplied corrupted DSS option; affected builds can desynchronize socket data, reset the connection, or panic when warnings are fatal.
