netlink message senders. A local attacker could send specially crafted
messages to udev in order to gain root privileges. (CVE-2009-1185)

Sebastian Krahmer discovered a buffer overflow in the path encoding
routines in udev. A local attacker could exploit this to crash udev,
leading to a denial of service. (CVE-2009-1186).
