RIOT-OS vulnerable to null pointer dereference during fragment forwarding

概要

RIOT-OS vulnerable to null pointer dereference during fragment forwarding

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

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. During forwarding of a fragment an uninitialized entry in the reassembly buffer is used. The NULL pointer dereference triggers a hard fault exception resulting in denial of service. Version 2022.10 fixes this issue. As a workaround, disable support for fragmented IP datagrams or apply the patches manually.
