CVE-2026-89937

iio: chemical: sgp30: Handle IAQ thread creation failure

Published Sep 16, 2026 CVSS n/a EPSS < 1% KEV · Not listed

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.
