2.9 · LOW
Published Dec 16, 2022 contiki-ng CWE-476 EPSS 0.21% (11th pctl)

Overview

CVE-2022-41972 is a low-severity vulnerability affecting contiki-ng contiki-ng. It was published on December 16, 2022 and has a CVSS 3.1 base score of 2.9 (LOW).

This vulnerability has a CVSS 3.1 base score of 2.9, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. Versions prior to 4.9 contain a NULL Pointer Dereference in BLE L2CAP module. The Contiki-NG operating system for IoT devices contains a Bluetooth Low Energy stack. An attacker can inject a packet in this stack, which causes the implementation to dereference a NULL pointer and triggers undefined behavior. More specifically, while processing the L2CAP protocol, the implementation maps an incoming channel ID to its metadata structure. In this structure, state information regarding credits is managed through calls to the function input_l2cap_credit in the module os/net/mac/ble/ble-l2cap.c. Unfortunately, the input_l2cap_credit function does not check that the metadata corresponding to the user-supplied channel ID actually exists, which can lead to the channel variable being set to NULL before a pointer dereferencing operation is performed. The vulnerability has been patched in the "develop" bran

Remediation

Check the references section for vendor advisories and patches from contiki-ng. Update contiki-ng 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.
