CVE-2009-1243 wrote:
net/ipv4/udp.c in the Linux kernel before 2.6.29.1 performs an unlocking step in certain incorrect circumstances, which allows local users to cause a denial of service (panic) by reading zero bytes from the /proc/net/udp file and unspecified other files, related to the "udp seq_file infrastructure."


Patches can be found here:
http://git.kernel.org/?p=linux/kernel/g ... 7be9313dbe

According to kernel release change-log, it is fixed in 2.6.29.1 release:
http://kernel.org/pub/linux/kernel/v2.6 ... g-2.6.29.1
