Linux disk/nic frontends data leaks T[his CNA information record relates to
multiple CVEs; the text explains which aspects/vulnerabilities correspond
to which CVE.] Linux Block and Network PV device frontends don’t zero
memory regions before sharing them with the backend (CVE-2022-26365,
CVE-2022-33740). Additionally the granularity of the grant table doesn’t
allow sharing less than a 4K page, leading to unrelated data residing in
the same 4K page as data shared with a backend being accessible by such
backend (CVE-2022-33741, CVE-2022-33742).
