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

The weakness is caused due to an error within the Transparent
Hugepage (THP) support in mm/huge_memory.c when MADV_HUGEPAGE regions
are configured and can be exploited to cause a kernel panic.

The weakness is reported in version 2.6.39.1. Other versions may also
be affected.

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
Reported by Caspar Zhang in a bug report.
