Overview

CVE-2023-24817 is a high-severity vulnerability. It was published on May 30, 2023 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

RIOT-OS, an operating system for Internet of Things (IoT) devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2023.04, an attacker can send a crafted frame to the device resulting in an integer underflow and out of bounds access in the packet buffer. Triggering the access at the right time will corrupt other packets or the allocator metadata. Corrupting a pointer will lead to denial of service. This issue is fixed in version 2023.04. As a workaround, disable SRH in the network stack.

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.
