Description OSIDB Bzimport 2026-09-17 17:07:30 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: dac: ad5686: missing NULL check on match data

Verify that chip_info pointer is not NULL. If a user binds the driver
using driver_override via sysfs with a device name not present in the
id_table or of_match_table, match data will be NULL.
