Description

The econet_sendmsg function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2, when an econet address is configured, allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a sendmsg call that specifies a NULL value for the remote address field.
