An out-of-bounds read can be triggered by 6LoWPAN packets sent to devices running Contiki-NG 4.6 and prior. The IPv6 header decompression function (&lt;code&gt;uncompress_hdr_iphc&lt;/code&gt;) does not perform proper boundary checks when reading from the packet buffer. Hence, it is possible to construct a compressed 6LoWPAN packet that will read more bytes than what is available from the packet buffer. As of time of publication, there is not a release with a patch available. Users can apply the patch for this vulnerability out-of-band as a workaround.</p> <p><strong>Affected:</strong> contiki-ng</p> <p>Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices.
