[FYI PATCH 0/3] CVE-2020-2732

[Paolo Bonzini]

vmx_check_intercept is not yet fully implemented by KVM on Intel processors,
causing e.g. the I/O or MSR interception bitmaps not to be checked.
In general we can just disallow instruction emulation on behalf of L1,
but this series also implements I/O port checks.
