Linux kernel is vulnerable to Denial Of Service (DoS). The vulnerability exists due to the null pointer dereference bug in the traffic control subsystem, allowing an attacker to cause an application crash via a crafted traffic control configuration that is set up with “tc qdisc” and “tc class” commands. This affects qdisc_graft function of sch_api.c
