Denial of Service Vulnerability in RIOT-OS Network Stack

CVE-2023-24822 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

RIOT-OS, an operating system that supports Internet of Things devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2022.10, an attacker can send a crafted frame to the device resulting in a NULL pointer dereference while encoding a 6LoWPAN IPHC header. The NULL pointer dereference causes a hard fault exception, leading to denial of service. Version 2022.10 fixes this issue. As a workaround, apply the patches manually.
