Title

RIOT-OS vulnerable to null pointer dereference during fragment forwarding

Summary

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.

Severity

7.5 (High)

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.

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."

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."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
