Vulnerability Details
The vulnerability CVE-2025-47406 stems from an information disclosure issue while processing IOCTL handler callbacks without proper verification of buffer size. This flaw can potentially allow attackers with local access to extract sensitive information.
The CVSS score of 6.1 indicates a medium severity level, emphasizing that while the vulnerability is not critical, it still requires prompt attention from security teams. The affected products include several firmware versions such as cologne_firmware, fastconnect_6700_firmware, and others.
The vulnerability was publicly disclosed on May 4, 2026, with a detailed description provided by Qualcomm. The CVE classification falls under CWE-125 and CWE-126, relating to improper handling of input and buffer sizes.
Technical Analysis
The root cause of CVE-2025-47406 is the lack of buffer size verification in IOCTL handler callbacks, leading to potential information disclosure. The attack vector is local, meaning that an attacker must have access to the system to exploit this vulnerability.
The attack complexity is low, with the required privileges being also low. This means that a malicious user with basic access rights can exploit this vulnerability without needing significant technical skills.
User interaction is not required, making it easier for attackers to leverage this vulnerability. The confidentiality impact is classified as high, while integrity and availability impacts are rated as none and low, respectively.
Risk & Impact Analysis
The real-world risk posed by CVE-2025-47406 is significant, particularly for organizations utilizing Qualcomm firmware in critical applications. The lack of buffer size verification could lead to unauthorized information access, potentially exposing sensitive data.
Given the high confidentiality impact, organizations need to assess the blast radius of this vulnerability within their networks. The potential for information leakage is a serious concern, especially in environments where sensitive data is processed.
Organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively. The urgency is further underscored by the fact that while no known exploits exist, the nature of the vulnerability allows for potential future exploitation.
