Description: A vulnerability has been reported in OpenBSD, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL pointer dereference error within the handling of SIOCGIFRTLABEL ioctls in sys/net/if.c and sys/net/route.c. This can be exploited to cause a kernel panic via an SIOCGIFRTLABEL ioctl call on interfaces without an assigned route label.
