Vulnerability from cvelistv5 – Published: 2020-07-07 20:15 – Updated: 2024-08-04 10:12

Title

Memory leak in wpanctl can lead to DoS

Summary

A memory leak in Openthread's wpantund versions up to commit 0e5d1601febb869f583e944785e5685c6c747be7, when used in an environment where wpanctl is directly interfacing with the control driver (eg: debug environments) can allow an attacker to crash the service (DoS). We recommend updating, or to restrict access in your debug environments.
