FKIE_CVE-2012-6657

Vulnerability from fkie_nvd - Published: 2014-09-28 10:55 - Updated: 2026-06-16 23:48
Severity
Summary
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.
