Vulnerability from github – Published: 2024-07-08 18:31 – Updated: 2025-11-04 18:31

Details

Two stack-based buffer overflow vulnerabilities exist in the boa set_RadvdInterfaceParam functionality of Realtek rtl819x Jungle SDK v3.4.11. A specially crafted series of network requests can lead to remote code execution. An attacker can send a sequence of requests to trigger these vulnerabilities.This stack-based buffer overflow is related to the AdvDefaultPreference request's parameter.

Severity

7.2 (High)
