These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.","published":"2022-09-29T03:15:11.000Z","lastModified":"2026-06-17T00:02:23.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-835"],"affected":["qemu/qemu","redhat/virtualization","redhat/enterprise linux desktop","redhat/enterprise linux eus","redhat/enterprise linux openstack platform","redhat/enterprise linux server","redhat/enterprise linux server aus","redhat/enterprise linux server tus","redhat/enterprise linux workstation"],"epss":{"score":0.00304,"percentile":0.22975,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.30%).
