CVE-2022-2196

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 ...

CVE-2022-2196

A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM L0 advertising eIBRS support to L1. An attacker at L2 with code...
