CVE-2025-8298 | Realtek RTL8811AU rtwlanu.sys N6CQueryInformationHandleCustomized11nOids Out-Of-Bounds Read Information Disclosure Vulnerability

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.

3.8 3.0 LOW
CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
