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...

CVE-2022-2196

The CVE-2022-2196 entry concerns a regression in Linux kernel KVM/nVMX where speculative execution could leak from an L2 guest to the host L1 due to inadequate Spectre v2 mitigations (retpolines/IBPB/eIBRS context). The description states an L2 attacker with code execution can influence indirect ...
