Detailsinfo

A vulnerability classified as critical was found in RIOT-OS. Affected by this vulnerability is some unknown functionality of the component 6LoWPAN Frame Handler. The manipulation with an unknown input leads to a integer underflow vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. The summary by CVE is:

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.

The weakness was shared 05/30/2023 as GHSA-xjgw-7638-29g5. It is possible to read the advisory at github.com. This vulnerability is known as CVE-2023-24817 since 01/30/2023. The technical details are unknown and an exploit is not publicly available.
