NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-xen package and not the kernel-xen package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.
