Description ljubomir inspur_group 2023-02-09 08:37:30 UTC 
Description of problem:
A flaw was found in the KVM's Intel nested virtualization feature (nVMX). Since L1 and L2 shared branch prediction modes (guest-user and guest-kernel), KVM did not protect indirect branches in L1 from steering by a malicious agent in L2. This could allow a malicious nested guest to carry out Spectre v2 attacks against L1 due to a missing IBPB at VM-exit time.
