CVE-2004-0230

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

EPSS

80% chance of exploitation in the next 30 days; higher than 99% of CVEs (scores of 2026-10-25)
