Stack consumption vulnerability in the do_page_fault function in
arch/x86/mm/fault.c in the Linux kernel before 2.6.28.5 allows local users
to cause a denial of service (memory corruption) or possibly gain
privileges via unspecified vectors that trigger page faults on a machine
that has a registered Kprobes probe.

The page fault handler could consume stack memory. A local attacker
could exploit this to crash the system or gain root privileges with a
Kprobe registered.
