Описание
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.
It was found that the Linux kernel's networking implementation did not correctly handle the setting of the keepalive socket option on raw sockets. A local user able to create a raw socket could use this flaw to crash the system.
Отчет
This issue does not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 7 and Red Hat Enterprise MRG 2. This issue affects the version of the kernel package as shipped with Red Hat Enterprise Linux 5 and 6. Future kernel updates for Red Hat Enterprise Linux 5 and 6 may address this issue.
