Vulnerability details
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume more server CPU to process.
Affected software
Linux kernel
