CVE-2025-47329 is a vulnerability classified under CWE-763 (Release of Invalid Pointer or Reference) affecting multiple Qualcomm Snapdragon platforms and wireless connectivity chips. The root cause is memory corruption triggered by improper handling of invalid inputs during the application info setup process. This flaw allows the system to release invalid pointers or references, which can corrupt memory and potentially enable attackers to execute arbitrary code, escalate privileges, or cause denial of service conditions. The affected products include a broad range of Snapdragon SoCs such as FastConnect 7800, QAM and QCA series chips, Snapdragon 8 Gen 3 Mobile Platform, Snapdragon AR1 Gen 1, Snapdragon W5+ Gen 1 Wearable Platform, and various WCD, WCN, and WSA wireless modules. The CVSS v3.1 base score is 7.8, indicating high severity, with attack vector limited to local access (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are known, the vulnerability's nature suggests that attackers with local access could leverage it to compromise device security. The vulnerability was published on September 24, 2025, and no patches are currently linked, emphasizing the need for vigilance and prompt remediation once fixes are released.

The vulnerability can have severe consequences for organizations and individuals using affected Qualcomm Snapdragon devices. Exploitation could lead to unauthorized code execution, allowing attackers to gain elevated privileges and potentially take full control of the device. This compromises confidentiality by exposing sensitive data, integrity by allowing unauthorized modifications, and availability by causing crashes or denial of service. Given the widespread use of Snapdragon chipsets in smartphones, tablets, wearables, and IoT devices, the impact could be extensive, affecting personal users, enterprises, and critical infrastructure relying on these devices. The local access requirement somewhat limits remote exploitation but does not eliminate risk, especially in environments where attackers can gain physical or local network access. The absence of known exploits currently provides a window for proactive mitigation, but the broad product range affected increases the potential attack surface significantly.

Organizations and users should monitor Qualcomm and device vendors for official patches addressing CVE-2025-47329 and apply them promptly once available. Until patches are released, minimizing local access to devices is critical; enforce strict physical security controls and limit local user privileges. Employ mobile device management (MDM) solutions to enforce security policies and monitor for suspicious activity. Disable or restrict unnecessary services and interfaces that could provide local access vectors. Conduct thorough security assessments on devices using affected Snapdragon platforms to identify potential exploitation attempts. For enterprises deploying IoT or wearable devices with these chipsets, segment networks to reduce exposure and implement anomaly detection systems. Additionally, educate users on the risks of installing untrusted applications or granting elevated permissions that could facilitate exploitation of this vulnerability.
