Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: adc: rzg2l_adc: Set driver data before enabling runtime PM<br /> <br /> When stress-testing the system by repeatedly unbinding and binding the ADC<br /> device in a loop, and the ADC is a supplier for another device (e.g., a<br /> thermal hardware block that reads temperature through the ADC), it may<br /> happen that the ADC device is runtime-resumed immediately after runtime PM<br /> is enabled, triggered by its consumer. At this point, since drvdata is not<br /> yet set and the driver&amp;#39;s runtime PM callbacks rely on it, a crash can<br /> occur. To avoid this, set drvdata just after it was allocated.
