NOTE: the vendor states \"Basically if you care about this attack vector, disable deduplication.\" Share-until-written approaches for memory conservation among mutually untrusting tenants are inherently detectable for information disclosure, and can be classified as potentially misunderstood behaviors rather than vulnerabilities."
