Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 5.15.167/6.1.112/6.6.54/6.10.13/6.11.2. Affected is the function adp5589_clear_config of the component adp5589-keys. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2024-49871 since 10/21/2024. There are known technical details, but no exploit is available.
