Description Marcus Meissner 2017-04-25 06:36:52 UTC 
CVE-2017-8106

The handle_invept function in arch/x86/kvm/vmx.c in the Linux kernel
3.12 through 3.15 allows privileged KVM guest OS users to cause a
denial of service (NULL pointer dereference and host OS crash) via a
single-context INVEPT instruction with a NULL EPT pointer.

Comment 1 Marcus Meissner 2017-04-25 06:38:01 UTC 
https://bugzilla.kernel.org/show_bug.cgi?id=195167

has the details.... 

This flaw was introduced in commit bfd0a56b90005f8c8a004baf407ad90045c2b11e
(nEPT: Nested INVEPT) and removed in 4b855078601fc422dbac3059f2215e776f49780f
(KVM: nVMX: Don't advertise single context invalidation for invept).
Therefore there should be two ways to fix this.
Comment 2 Joerg Roedel 2017-05-02 16:17:23 UTC 
Only SLE12-SP1 is affected. I'll backport the fix.
Comment 3 Joerg Roedel 2017-05-02 20:53:29 UTC

> Only SLE12-SP1 is affected. I'll backport the fix.

Backported to cve/linux-3.12 and pushed for inclusion.
Comment 4 Joerg Roedel 2017-05-03 12:33:54 UTC 
Branch is merged to cve/linux-3.12. Assigning back.
