I sent this mail to Greg KH (2.6.27.y maintainer), he sent me:

"Can you get the kvm maintainers to agree that this is correct?

thanks,

So the bug :

I found a memory allocation bug in kvm/mmu.c&  kvm_main.c. /in
kvm_destroy_vm()/

Affected kernel: 2.6.27.32-2.6.27.41

Mainline kernel (2.6.32) is not affected. (Modified kvm subsystem.)

Cause:
http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fstable%2Flinux-2.6.27.y.git;a=commitdiff_plain;h=d2127c8300fb1ec54af56faee17170e7a525326d

Solution: Revert this patch.

This bug can cause local DoS in the host system.



Looks like some other patch is missing in 2.6.27.y.  Not sure what it is.

But it's safer to revert this patch for now.
