CVE-2022-33742

Summary: CVE-2022-33742 is tied to Linux Block and Network PV frontends leaking data due to sharing memory regions without zeroing and because grant-table granularity may expose data within the same 4K page as data shared with a backend. This is described alongside related CVEs (CVE-2022-26365, C...
