Short explanation
Lack of source verification in the IPv6 Router Advertisement handler allows a remote attacker to manipulate the default gateway and address configuration of the target device. Affected versions are up to 4.4.1; a fix is available in V4.4.2.
Abuse of network configuration can jeopardize device communication and security.
What should be done?
- Upgrade FreeRTOS‑Plus‑TCP to V4.4.2
- Review Amazon security bulletin and patch notes
- Enable Router Advertisement validation if supported

Show the technical text from the sources
Improper verification of the source of a communication channel in the IPv6 Router Advertisement handler in Amazon FreeRTOS-Plus-TCP before V4.4.2 might allow a remote third-party to influence an endpoint's IPv6 default gateway, on-link prefix, and address configuration via a crafted Router Advertisement. To remediate this issue, users should upgrade to version V4.4.2.
