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.

CVE-2009-3726 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Linux kernel vulnerabilities
It was discovered that the AX.25 network subsystem did not correctly
check integer signedness in certain setsockopt calls. A local attacker
could exploit this to crash the system, leading to a denial of service.
Ubuntu 9.10 was not affected. (CVE-2009-2909)
Jan Beulich discovered that the kernel could leak register contents to
32-bit processes that were switched to 64-bit mode. A local attacker
could run a specially crafted binary to read register values from an
earlier process, leading to a loss of privacy. (CVE-2009-2910)
Dave Jones discovered that the gdth SCSI driver did not correctly validate
array indexes in certain ioctl calls. A local attacker could exploit
this to crash the system or gain elevated privil
