Astra Linux – Vulnerability in Linux 5.10

There is a vulnerability in the Linux Kernel within the KVM framework: nVMX, which allows for speculative execution attacks. L2 can execute Spectre v2 attacks on L1, as L1 believes it does not need retpolines or IBPB after executing L2, due to KVM L0 indicating support for eIBRS to L1. An attacke...
