DESCRIPTION

* CVE-2017-7518: Privilege escalation in KVM emulation subsystem.

An implementation error in the syscall instruction emulation in KVM
leads to a kernel exception raised in userspace. A user/process inside
guest could use this flaw to potentially escalate their privileges
inside guest.


* CVE-2017-12188: Out-of-bounds memory access during KVM page table walk.

A logic error in the page table management of KVM guests can result in
an out-of-bounds memory access. A guest virtual machine could use this
flaw to crash the host or potentially execute malicious code with host
privileges.
