CVE-2015-7513

Priority
Medium
Description
arch/x86/kvm/x86.c in the Linux kernel before 4.4 does not reset the PIT
counter values during state restoration, which allows guest OS users to
cause a denial of service (divide-by-zero error and host OS crash) via a
zero value, related to the kvm_vm_ioctl_set_pit and kvm_vm_ioctl_set_pit2
functions.
Ubuntu-Description
It was discovered that the KVM implementation in the Linux kernel did not
properly restore the values of the Programmable Interrupt Timer (PIT). A
user-assisted attacker in a KVM guest could cause a denial of service in
the host (system crash).
