Summary
The Transmission Control Protocol (TCP) allows remote attackers to cause a denial of service (bandwidth consumption) by sending ACK messages for packets that have not yet been received (optimistic ACKs), which can cause the sender to increase its transmission rate until it fills available bandwidth.
Exploit prediction
2.32% chance of exploitation in the next 30 days, higher than 83% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
