CVE-2025-47367 is a vulnerability classified under CWE-787 (Out-of-bounds Write) affecting multiple Qualcomm Snapdragon products, including FastConnect 6700/6900/7800 modules, Snapdragon 7c+ Gen 3 and 8cx Gen 3 Compute Platforms, various WCD and WSA audio chips, and Qualcomm Video Collaboration VC3 Platform. The flaw arises from improper bounds checking during IOCTL (Input/Output Control) processing, which allows an attacker with low-level privileges to perform a memory corruption via an out-of-bounds write operation. This can lead to arbitrary code execution, privilege escalation, or denial of service by corrupting critical memory structures. The vulnerability has a CVSS 3.1 base score of 7.8, indicating high severity, with attack vector Local (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). The affected components are widely integrated into mobile devices, IoT endpoints, and compute platforms, making the attack surface extensive. No patches or known exploits are currently available, but the vulnerability’s nature suggests potential for impactful exploitation once weaponized. The vulnerability was reserved in May 2025 and published in November 2025, indicating recent discovery and disclosure.

The impact of CVE-2025-47367 is significant due to the broad range of affected Qualcomm Snapdragon components embedded in millions of consumer and enterprise devices worldwide. Exploitation can lead to full system compromise, including unauthorized data access, manipulation, or destruction, and disruption of device availability. This can affect smartphones, tablets, laptops, IoT devices, and specialized compute platforms relying on these chips. For organizations, this translates into risks of data breaches, operational outages, and potential lateral movement within networks if compromised devices are connected to corporate environments. Critical infrastructure and sectors relying on secure communications and processing, such as telecommunications, healthcare, and finance, are particularly vulnerable. The local attack vector 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 high severity score demands urgent attention.

To mitigate CVE-2025-47367, organizations should implement the following specific measures: 1) Restrict local access to devices with affected Qualcomm components by enforcing strong physical security and limiting administrative privileges. 2) Monitor and audit IOCTL calls and device driver interactions for anomalous or unauthorized activity that could indicate exploitation attempts. 3) Employ endpoint detection and response (EDR) solutions capable of detecting memory corruption and unusual kernel-level behavior. 4) Coordinate with device and hardware vendors to obtain and apply patches or firmware updates as soon as they become available. 5) For enterprise environments, segment networks to isolate vulnerable devices and reduce the risk of lateral movement. 6) Educate users and administrators about the risks of local privilege escalation and enforce strict device usage policies. 7) Consider deploying runtime application self-protection (RASP) or memory protection technologies where feasible to mitigate exploitation impact. 8) Maintain up-to-date inventories of affected hardware to prioritize patching and monitoring efforts.
