CVE-2026-89475

In the Linux kernel, the following vulnerability has been resolved:

power: supply: bq24257: fix use-after-free on remove

The STAT-pin interrupt is devm-managed, so it stays armed until the devm cleanup that runs after remove() returns. remove() cancels bq->iilimit setup work while the threaded handler can still fire; that handler reschedules the work and dereferences bq, so the work runs against freed memory once devm frees bq.

Make the delayed work device-managed with devm delayed work autocancel(), registered before the interrupt request. The devm cleanup then releases the interrupt first, so the handler can no longer reschedule the work, and cancels the work before bq is freed. The explicit cancel delayed work sync() in remove() is no longer needed and is dropped.
