CVE-2025-8302 (GCVE-0-2025-8302)

Vulnerability from nvd – Published: 2025-09-02 20:02 – Updated: 2025-09-03 15:29

Title

Realtek rtl81xx SDK Wi-Fi Driver rtwlanu Heap-based Buffer Overflow Local Privilege Escalation Vulnerability

Summary

Realtek rtl81xx SDK Wi-Fi Driver rtwlanu Heap-based Buffer Overflow Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Realtek rtl81xx SDK Wi-Fi driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the N6CSet_DOT11_CIPHER_DEFAULT_KEY function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-26553.

Severity

CVE-2025-8300 (GCVE-0-2025-8300)

Vulnerability from cvelistv5 – Published: 2025-09-02 20:02 – Updated: 2025-09-03 14:32

Title

Realtek rtl81xx SDK Wi-Fi Driver rtwlanu Heap-based Buffer Overflow Local Privilege Escalation Vulnerability

Summary

Realtek rtl81xx SDK Wi-Fi Driver rtwlanu Heap-based Buffer Overflow Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Realtek rtl81xx SDK Wi-Fi driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the N6CSet_DOT11_CIPHER_DEFAULT_KEY function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-26552.

Severity

8.8 (High)
