This results in an invalid memory\naccess in the next iteration of the loop since victim_name.len was not\ninitialized to the length of the name of the current extref.\n\nFix this by initializing victim_name.len with the current extref's name\nlength.","published":"2025-07-25T13:15:27.000Z","lastModified":"2026-07-30T06:23:11.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","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-908"],"affected":["linux/linux kernel","debian/debian linux"],"epss":{"score":0.00201,"percentile":0.0992,"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 (0.20%).
