CVE-2023-31346
PUBLISHED
Es bestehen mehrere Schwachstellen in AMD SEV-SNP Firmware für Prozessoren. Diese Fehler bestehen in der SEV-Firmware aufgrund eines Codefehlers und eines Fehlers bei der Speicherinitialisierung, der es ermöglicht, auf veraltete Daten von anderen Gästen zuzugreifen und eine falsche TSC zu beobachten, wenn Secure TSC aktiviert ist. Ein lokaler, privilegierter Angreifer kann diese Schwachstellen ausnutzen, um vertrauliche Informationen offenzulegen.
