there are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges. (
( CVE-2022-2318) 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 dont zero memory regions before sharing them with the backend (cve-2022-26365,( CVE-2022-33740).
Additionally the granularity of the grant table doesnt 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). (
