CVE-2020-27302 describes a stack buffer overflow vulnerability in Realtek RTL8710 and other Ameba-based devices, allowing remote code execution. An attacker within Wi-Fi range can trigger this by sending a specially crafted "Encrypted GTK" value during the WPA2 4-way handshake. This vulnerability carries a high CVSS score of 8.0, indicating a severe impact with high confidentiality, integrity, and availability compromise, requiring only adjacent network access and low privileges. While no active exploitation or public exploit code is currently reported, and community discussion is minimal, the potential for remote code execution makes it a significant concern for affected Realtek products.
