CVE-2024-58009

5.5 · MEDIUM
Published Feb 27, 2025 linux CWE-476 EPSS 0.20% (10th pctl)

Overview

CVE-2024-58009 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 27, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc

A NULL sock pointer is passed into l2cap_sock_alloc() when it is called

from l2cap_sock_new_connection_cb() and the error handling paths should

also be aware of it.

Seemingly a more elegant solution would be to swap bt_sock_alloc() and

l2cap_chan_create() calls since they are not interdependent to that moment

but then l2cap_chan_create() adds the soon to be deallocated and still

dummy-initialized channel to the global list accessible by many L2CAP

paths. The channel would be removed from the list in short period of time

but be a bit more straight-forward here and just check for NULL instead of

changing the order of function calls.

Found by Linux Verification Center (linuxtesting.org) with SVACE static

analysis tool.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
