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 ...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. The Linux kernel suffers from a security vulnerability that stems from nVMX allowing speculative execution attacks where L2 can execute a Spectre v2 attack against L1 because L1 believes it does not...
