kernel: KVM: SEV-ES / SEV-SNP VMGEXIT double fetch vulnerability

A flaw was found in KVM AMD Secure Encrypted Virtualization SEV in the Linux kernel. A KVM guest using SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the VMGEXIT handler recursively. If an attacker manages to call the handler multiple time...

The vulnerability of the SEV-SNP and SEV-ES mechanisms in Linux operating systems allows attackers to compromise the confidentiality and integrity of protected information.

The vulnerability of the SEV-SNP and SEV-ES mechanisms in Linux operating systems stems from incorrect neutralization of special elements in the output data used by the incoming component. Exploiting this vulnerability allows an attacker to compromise the confidentiality and integrity of the...
