Detailsinfo

A vulnerability was found in RIOT-OS. It has been rated as critical. This issue affects some unknown functionality of the component 6LoWPAN Frame Handler. The manipulation with an unknown input leads to a integer underflow vulnerability. Using CWE to declare the problem leads to CWE-191. The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result. Impacted is availability. The summary by CVE is:

RIOT-OS, an operating system that supports Internet of Things devices, contains a network stack with the ability to process 6LoWPAN frames. An attacker can send a crafted frame to the device resulting in a large out of bounds write beyond the packet buffer. The write will create a hard fault exception after reaching the last page of RAM. The hard fault is not handled and the system will be stuck until reset. Thus the impact is denial of service. Version 2022.10 fixes this issue. As a workaround, apply the patch manually.

The weakness was published 04/24/2023 as GHSA-vpx8-h94p-9vrj. The advisory is shared at github.com. The identification of this vulnerability is CVE-2023-24820 since 01/30/2023. Neither technical details nor an exploit are publicly available.
