CVE-2021-47230

CVE-2021-47230 affects the Linux kernel KVM on x86. The vulnerability arises from a lack of synchronization between the vCPU SMM flag and the MMU’s SMM flag, so that when RSM is not emulated correctly, KVM can bail out and leave the MMU in an inconsistent state. This misalignment can cause a NULL...
