This causes the clock\nrate to become bogus or even zero (possibly due to the P divider being\n1, leading to a divide-by-zero).\n\nFix this by incorporating the P divider offset into the calculation.","published":"2025-10-09T10:15:32.000Z","lastModified":"2026-10-19T21:10:00.000Z","status":"Analyzed","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-369"],"affected":["linux/linux kernel"],"epss":{"score":0.00127,"percentile":0.02388,"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":"low","text":"Lower severity and a low EPSS score (0.13%).
