+Subject: KVM: x86: work around leak of uninitialized stack contents
+ (CVE-2019-7222)
+Origin: https://git.kernel.org/linus/353c0956a618a07ba4bbe7ad00ff29fe70e8412a
+Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2019-7222
+
+Bugzilla: 1671930
+
+Emulation of certain instructions (VMXON, VMCLEAR, VMPTRLD, VMWRITE with
+memory operand, INVEPT, INVVPID) can incorrectly inject a page fault
+when passed an operand that points to an MMIO address.  The page fault
+will use uninitialized kernel stack memory as the CR2 and error code.
+
+The right behavior would be to abort the VM with a KVM_EXIT_INTERNAL_ERROR
+exit to userspace; however, it is not an easy fix, so for now just
+ensure that the error code and CR2 are zero.
+
+Embargoed until Feb 7th 2019.
