Описание
Failure to initialize
memory in SEV Firmware may allow a privileged attacker to access stale data
from other guests.
A flaw was found in some AMD CPUs where the guest message responses have not been zero-initialized. This issue may allow a local attacker with the ability to run arbitrary code on a container or virtual machine to discover sensitive information contained in the host system's memory.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
