The driver uses wdt_freq as a\ndivisor directly in airoha_wdt_probe() to compute max_timeout and in\nairoha_wdt_get_timeleft() to compute the remaining time, which results\nin a division by zero.\n\nAdd a check for wdt_freq == 0 in probe and return -EINVAL with\ndev_err_probe() to prevent the division by zero and provide a\ndiagnostic message.","published":"2026-08-10T13:20:28.000Z","lastModified":"2026-08-17T06:17:44.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00166,"percentile":0.05801,"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":"unknown","text":"Not yet scored.
