CVE-2025-8298

Realtek RTL8811AU rtwlanu.sys N6CQueryInformationHandleCustomized11nOids Out-Of-Bounds Read Information Disclosure Vulnerability

3.8 Low

Realtek RTL8811AU rtwlanu.sys N6CQueryInformationHandleCustomized11nOids Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows local attackers to disclose sensitive information on affected installations of Realtek RTL8811AU drivers. 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 N6CQueryInformationHandleCustomized11nOids function. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. Was ZDI-CAN-25864.
