CVE-2021-23270 (GCVE-0-2021-23270)

Vulnerability from cvelistv5 – Published: 2021-04-12 17:40 – Updated: 2024-08-03 19:05

Summary

In Gargoyle OS 1.12.0, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set.

Severity
