kernel: kvm: vmx: invept vm exit not handled

It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invept Invalidate Translations Derived from EPT instructions. On hosts with an Intel processor and invept VM exit support, an unprivileged guest user could use these instructions to crash the guest...

DEBIAN-CVE-2014-9066

Xen 4.4.x and earlier, when using a large number of VCPUs, does not properly handle read and write locks, which allows local x86 guest users to cause a denial of service write denial or NMI watchdog timeout and host crash via a large number of read requests, a different vulnerability than...
