An attacker with root access to a guest partition can read a limited amount of hypervisor memory, potentially exposing sensitive data belonging to the hypervisor or other guest partitions hosted on the same system, resulting in a confidentiality impact. The attacker has no control over which memory contents are returned. This vulnerability is of particular concern in multi-tenant environments where guests may run arbitrary OS images.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":18,"depthScoreParts":{"impact":17.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
