Description

Rodrigo Freire discovered a flaw in the Linux kernel's TCP illinois congestion control algorithm. A local attacker could use this to cause a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
