Linux kernel is vulnerable to information disclosure. This occurs in arch/x86/kvm/emulate.c in the Linux kernel. Local users could obtain sensitive information from kernel memory or cause a denial of service (use-after-free) via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt.
