Overview

CVE-2024-36009 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 20, 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:

ax25: Fix netdev refcount issue

The dev_tracker is added to ax25_cb in ax25_bind(). When the

ax25 device is detaching, the dev_tracker of ax25_cb should be

deallocated in ax25_kill_by_device() instead of the dev_tracker

of ax25_dev. The log reported by ref_tracker is shown below:
