Overview

CVE-2024-26653 is a high-severity vulnerability. It was published on April 1, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

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:

usb: misc: ljca: Fix double free in error handling path

When auxiliary_device_add() returns error and then calls

auxiliary_device_uninit(), callback function ljca_auxdev_release

calls kfree(auxdev->dev.platform_data) to free the parameter data

of the function ljca_new_client_device. The callers of

ljca_new_client_device shouldn't call kfree() again

in the error handling path to free the platform data.

Fix this by cleaning up the redundant kfree() in all callers and

adding kfree() the passed in platform_data on errors which happen

before auxiliary_device_init() succeeds .

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.
