We were just lucky so far since we used only a couple of PDIs\nand remained within the PDI array bounds.\n\nA Fixes: tag is not provided since there are no known platforms where\nthe out-of-bounds would be accessed, and the initial code had problems\nas well.\n\nA follow-up patch completely removes this useless offset.","published":"2024-06-21T11:15:12.000Z","lastModified":"2026-10-15T01:18:32.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"},"cwe":["CWE-125"],"affected":["linux/linux kernel"],"epss":{"score":0.00235,"percentile":0.14311,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%).
