Linux Kernel up to 6.1.4 rndis_query integer overflow

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability has been found in Linux Kernel up to 6.1.4 and classified as critical. This affects the function rndis_query. This manipulation causes integer overflow. This vulnerability is handled as CVE-2023-54110. There is not any exploit available. The affected component should be upgraded.

Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.1.4. Affected by this vulnerability is the function rndis_query. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: usb: rndis_host: Secure rndis_query check against int overflow Variables off and len typed as uint32 in rndis_query function are controlled by incoming RNDIS response message thus their value may be manipulated. Setting off to a unexpectetly large value will cause the sum with len and 8 to overflow and pass the implemented validation step. Consequently the response pointer will be referring to a location past the expected buffer boundaries allowing information leakage e.g. via RNDIS_OID_802_3_PERMANENT_ADDRESS OID.

It is possible to read the advisory at git.kernel.org. This vulnerability is known as CVE-2023-54110 since 12/24/2025. The exploitation appears to be easy. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/03/2026).

The vulnerability scanner Nessus provides a plugin with the ID 279878 (Linux Distros Unpatched Vulnerability : CVE-2023-54110), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 4.14.303, 4.19.270, 5.4.229, 5.10.163, 5.15.87, 6.0.19 or 6.1.5 eliminates this vulnerability. Applying the patch 55782f6d63a5a3dd3b84c1e0627738fc5b146b4e/ebe6d2fcf7835f98cdbb1bd5e0414be20c321578/232ef345e5d76e5542f430a29658a85dbef07f0b/11cd4ec6359d90b13ffb8f85a9df8637f0cf8d95/39eadaf5611ddd064ad1c53da65c02d2b0fe22a4/a713602807f32afc04add331410c77ef790ef77a/c7dd13805f8b8fc1ce3b6d40f6aff47e66b72ad2 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
