VERIFY ADVISORY:
http://secunia.com/advisories/38718/

DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service).

The vulnerability is caused due to a division by zero within the
"azx_position_ok()" function in sound/pci/hda/hda_intel.c, which can
be exploited to crash the system.

Note: Successful exploitation may require that the hda-intel driver
is used.

The vulnerability is reported in version 2.6.32.7 and 2.6.33-rc6 on a
system using the AMD780V chipset. Other versions may also be affected.

SOLUTION:
Fixed in the GIT repository.
