CVE-2024-49871 Information

Description

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.
