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.

A flaw was found in the Linux kernel's `tmp006` temperature sensor driver. This vulnerability occurs because the driver incorrectly handles the registration and de-registration of a hardware trigger. When the module is unloaded, a pointer to freed memory remains active, creating a 'dangling pointer'. This can lead to system instability or potentially allow an attacker to cause a denial of service.
