CVE-2012-4565

Priority
Description
The tcp_illinois_info function in net/ipv4/tcp_illinois.c in the Linux
kernel before 3.4.19, when the net.ipv4.tcp_congestion_control illinois
setting is enabled, allows local users to cause a denial of service
(divide-by-zero error and OOPS) by reading TCP stats.
Ubuntu-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.
