Last modified

CVE-2012-4565 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
