TITLE:
Linux Kernel "do_pages_move()" Information Disclosure and Denial of
Service

SECUNIA ADVISORY ID:
SA38502

VERIFY ADVISORY:
http://secunia.com/advisories/38502/

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 disclose potentially sensitive information.

The vulnerability is caused due to the "do_pages_move()" function in
mm/migrate.c not properly verifying the node values received from
userspace, which can be exploited to cause a crash or disclose memory
via a specially crafted "move_pages" system call.

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
Ramon de Carvalho Valle
