If the driver is unbound through sysfs, rather then the module being\n   rmmod-ed, this changes poll_interval unexpectedly\n\n2. This is racy, after it being set poll_interval could be changed\n   before bq27xxx_battery_update() checks it through\n   /sys/module/bq27xxx_battery/parameters/poll_interval\n\nFix this by added a removed attribute to struct bq27xxx_device_info and\nusing that instead of setting poll_interval to 0.\n\nThere also is another poll_interval related race on remove(), writing\n/sys/module/bq27xxx_battery/parameters/poll_interval will requeue\nthe delayed_work item for all devices on the bq27xxx_battery_devices\nlist and the device being removed was only removed from that list\nafter cancelling the delayed_work item.\n\nFix this by moving the removal from the bq27xxx_battery_devices list\nto before cancelling the delayed_work item.","published":"2025-12-24T13:16:10.000Z","lastModified":"2026-08-04T10:19:28.000Z","status":"Deferred","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00166,"percentile":0.05793,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%).
