CVE-2021-47062

The CVE-2021-47062 vulnerability affects the Linux kernel KVM SVM path. The issue occurs when iterating vCPUs for SEV-encrypted VMSAs using created_vcpus, which does not guarantee a vCPU’s existence and can trigger a NULL pointer dereference. The documented fix switches to iterating with online_v...

CVE-2021-47062 KVM: SVM: Use online_vcpus, not created_vcpus, to iterate over vCPUs

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Use onlinevcpus, not createdvcpus, to iterate over vCPUs Use the kvmforeachvcpu helper to iterate over vCPUs when encrypting VMSAs for SEV, which effectively switches to use onlinevcpus instead of createdvcpus.
