A flaw was found in Linux kernel’s KVM virtualization subsystem. The VMX
code does not restore the GDT.LIMIT to the previous host value, but instead
sets it to 64KB. With a corrupted GDT limit a host’s userspace code has an
ability to place malicious entries in the GDT, particularly to the per-cpu
variables. An attacker can use this to escalate their privileges.
