Overview

CVE-2024-36973 is a high-severity vulnerability. It was published on June 17, 2024 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

misc: microchip: pci1xxxx: fix double free in the error handling of gp_aux_bus_probe()

When auxiliary_device_add() returns error and then calls

auxiliary_device_uninit(), callback function

gp_auxiliary_device_release() calls ida_free() and

kfree(aux_device_wrapper) to free memory. We should't

call them again in the error handling path.

Fix this by skipping the redundant cleanup functions.

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.
