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) and potentially gain escalated privileges.

The vulnerability is caused due to an integer truncation error within
the "ioc_general()" function in drivers/scsi/gdth.c, which can be
exploited to cause a kernel memory corruption by sending specially
crafted IOCTLs.

Successful exploitation may require a 64bit system.

SOLUTION:
Fixed in the GIT repository.
