Description
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.
