Description

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

iio: temperature: tmp006: use devm_iio_trigger_register

tmp006_probe() allocates the DRDY trigger with devm_iio_trigger_alloc() but registers it with plain iio_trigger_register(). The driver has no .remove() callback, so on module unload the trigger stays in the global trigger list while its memory is freed by devm, leaving a dangling entry.

Switch to devm_iio_trigger_register() so the registration is undone in the same devm scope as the allocation.
