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. Found by static analysis.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
