CVE-2009-3722

First published: Thu Oct 29 2009(Updated: )

Quote from the upstream commit: Debug registers may only be accessed from cpl 0. Unfortunately, vmx will code to emulate the instruction even though it was issued from guest userspace, possibly leading to an unexpected trap later. Introduced in v2.6.30-rc1; Fixed in v2.6.32-rc1. <a href="http://git.kernel.org/linus/0a79b009525b160081d75cef5dbf45817956acf2">http://git.kernel.org/linus/0a79b009525b160081d75cef5dbf45817956acf2</a>
