Vulnerability Title
iio: chemical: sgp30: Handle IAQ thread creation failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: iio: chemical: sgp30: Handle IAQ thread creation failure kthread_run() can fail and return an error pointer, but sgp_probe() stores it and returns success, so the device is registered without its IAQ thread and sgp_remove() later passes the error pointer to kthread_stop(). Return the error from probe instead.
