Summary A race-condition flaw was discovered in the kernel's netlink module creation, which can trigger a kernel panic in netlink_release->module_put for local users creating netlink sockets. The flaw is specific to Red Hat Enterprise Linux and does not affect upstream kernels. The nfnetlink_log module must be loaded before the flaw can occur. Race condition in the kernel in Red Hat Enterprise Linux 7, kernel-rt and Red Hat Enterprise MRG 2, when the nfnetlink_log module is loaded, allows local users to cause a denial of service (panic) by creating netlink sockets.
