A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC
IRQ. This issue makes it possible for a misbehaving VMM to write to
SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an
unprivileged local attacker on the host to issue specific ioctl calls,
causing a kernel oops condition that results in a denial of service.
