DESCRIPTION:
A vulnerability has been reported in KVM, which can be exploited by
malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to an error when handling the
X86_CR4_OSXSAVE bit upon guest enter and can be exploited to cause a
crash via KVM_SET_SREGS IOCTL.
Successful exploitation requires a host without the XSAVE feature
support.
