CVE-2008-0384: OpenBSD

Medium severity, CVSS 4.9. EPSS: 0.8% chance of exploitation in the next 30 days.

OpenBSD 4.2 allows local users to cause a denial of service (kernel panic) by calling the SIOCGIFRTLABEL IOCTL on an interface that does not have a route label, which triggers a NULL pointer dereference when the return value from the rtlabel_id2name function is not checked.
