CVE-2025-8302 describes a heap-based buffer overflow vulnerability in the Realtek rtl81xx SDK Wi-Fi driver, specifically within the N6CSet_DOT11_CIPHER_DEFAULT_KEY function. This flaw affects Realtek rtl8811au and Wi-Fi USB drivers, allowing a local attacker to escalate privileges. The vulnerability has a CVSS score of 8.8 (High), indicating a significant risk. It requires local access and low privileges (AV:L/PR:L) but can lead to complete compromise of confidentiality, integrity, and availability (C:H/I:H/A:H) by allowing arbitrary code execution as SYSTEM. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is it listed in CISA's KEV catalog, suggesting it is not being actively exploited in the wild. Community discussion and media coverage are minimal, which is typical for most CVEs.
