Details

Ken Johnson and Jann Horn independently discovered that microprocessors utilizing
speculative execution of a memory read may allow unauthorized memory reads via
sidechannel attacks. An attacker in the guest could use this to expose sensitive
guest information, including kernel memory. This update allows QEMU to expose new
CPU features added by microcode updates to guests on amd64 and i386.
