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...
