Last modified
CVE-2012-6657 is a vulnerability of currently unknown severity. The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5.7 does not ensure that a keepalive action is associated with a stream socket, which allows local users to cause a denial of service (system crash) by leveraging the ability to create a raw socket.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
