Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

In the Linux kernel, the following vulnerability has been resolved:

Input: adp5589-keys - fix NULL pointer dereference

We register a devm action to call adp5589_clear_config() and then pass the i2c client as argument so that we can call i2c_get_clientdata() in order to get our device object. However, i2c_set_clientdata() is only being set at the end of the probe function which means that we'll get a NULL pointer dereference in case the probe function fails early.
