This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

HID: elan: Fix potential double free in elan_input_configured

'input' is a managed resource allocated with devm_input_allocate_device(),

so there is no need to call input_free_device() explicitly or

there will be a double free.

According to the doc of devm_input_allocate_device():

* Managed input devices do not need to be explicitly unregistered or

* freed as it will be done automatically when owner device unbinds from

* its driver (or binding fails).

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
