The delayed work uec->work is scheduled in gaokun_ucsi_probe()
but never properly canceled in gaokun_ucsi_remove(). This creates
use-after-free scenarios where the ucsi and gaokun_ucsi structure
are freed after ucsi_destroy() completes execution, while the
gaokun_ucsi_register_worker() might be either currently executing
or still pending in the work queue. The already-freed gaokun_ucsi
or ucsi structure may then be accessed.

Furthermore, the race window is 3 seconds, which is sufficiently
long to make this bug easily reproducible. The following is the

Add disable_delayed_work_sync() in gaokun_ucsi_remove() to ensure
that uec->work is properly canceled and prevented from executing
after the ucsi and gaokun_ucsi structure have been deallocated.

usb: typec: ucsi: fix probe failure in gaokun_ucsi_probe() 2025-11-26T11:59:21+00:00 Duoming Zhou duoming@zju.edu.cn 2025-11-25T10:36:26+00:00 6b120ef99fbcba9e413783561f8cc160719db589 The gaokun_ucsi_probe() uses ucsi_create() to allocate a UCSI instance. The ucsi_create() validates whether ops->poll_cci is defined, and if not, it directly returns -EINVAL. However, the gaokun_ucsi_ops structure does not define the poll_cci, causing ucsi_create() always fail with -EINVAL.
