Details

A Denial of Service vulnerability was detected in the stack segment
fault handler. A local attacker could exploit this by causing stack
fault exceptions under special circumstances (scheduling), which lead
to a kernel crash. (CAN-2005-1767)

Vasiliy Averin discovered a Denial of Service vulnerability in the
“tiocgdev” ioctl call and in the “routing_ioctl” function. By calling
fget() and fput() in special ways, a local attacker could exploit this
to destroy file descriptor structures and crash the kernel.
