However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parse_option() function, leading grub to crash or, in some rare scenarios, corrupt the IVT data.","published":"2025-02-18T20:15:19.000Z","lastModified":"2026-10-21T21:17:30.000Z","status":"Deferred","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":5.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:H"},"cwe":["CWE-252"],"affected":[],"epss":{"score":0.00292,"percentile":0.21623,"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 (0.29%).
