Name of the Vulnerable Software and Affected Versions Contiki-NG versions prior to 4.9

Description The issue is caused by insufficient control of the lengths for DIO and DAO messages, particularly when they contain RPL sub-option headers, allowing an attacker to trigger out-of-bounds reads in the RPL-Lite implementation of the RPL protocol in the Contiki-NG operating system.

Recommendations For versions prior to 4.9, upgrade to Contiki-NG 4.9 to resolve the issue. For users unable to upgrade, manually apply the code changes in PR #2484 as a temporary workaround.
