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). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33742)

- Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially
leading to information disclosure. (CVE-2022-23825)

under certain microarchitecture-dependent conditions. (CVE-2022-29900)
