What is CVE-2023-50927?

The Contiki-NG operating system, designed for Next-Generation IoT devices, is vulnerable due to out-of-bounds read conditions stemming from inadequate management of message lengths in its RPL-Lite protocol implementation.

Users are recommended to upgrade to Contiki-NG 4.9 where this issue has been addressed. Users who are unable to upgrade should consider applying the changes from PR #2484 manually to mitigate risks.
