CVE-2014-3610
First published: Sun Sep 21 2014(Updated: )
If the guest writes a noncanonical value to certain MSR registers, KVM will write that value to the MSR in the host context and a #GP will be raised leading to kernel panic. A privileged guest user can use this flaw to crash the host. Enabling CONFIG_PARAVIRT when building the kernel mitigates this issue because wrmsrl() ends up invoking safe msr write variant. Acknowledgements: Red Hat would like to thank Lars Bull of Google and Nadav Amit for reporting this issue.
