CVE-2025-47336 is a use-after-free vulnerability classified under CWE-416, discovered in Qualcomm Snapdragon chipsets, specifically impacting a broad range of models including FastConnect 7800, QMP1000, SM8735, SM8750, and various WCD, WCN, and WSA series components. The flaw occurs due to improper memory management during sensor register read operations, where memory is freed prematurely or accessed after being freed, leading to memory corruption. This corruption can be exploited to manipulate program execution flow, potentially allowing an attacker to execute arbitrary code with elevated privileges, corrupt data, or cause system crashes (denial of service). The vulnerability requires local access with high privileges (PR:H) but does not require user interaction (UI:N), and the attack vector is local (AV:L). The CVSS v3.1 score is 6.7, indicating a medium severity level, with high impact on confidentiality, integrity, and availability. No public exploits have been reported yet, but the vulnerability's presence in widely deployed Snapdragon chipsets used in mobile devices, IoT devices, and embedded systems makes it a significant concern. The lack of available patches at the time of publication necessitates immediate attention from affected parties to monitor vendor updates and prepare mitigation strategies.

For European organizations, the impact of CVE-2025-47336 can be substantial, particularly for those relying on mobile devices, embedded systems, or IoT infrastructure powered by affected Qualcomm Snapdragon chipsets. The vulnerability can lead to unauthorized code execution, data breaches, and service disruptions, undermining confidentiality, integrity, and availability of critical systems. Industries such as telecommunications, manufacturing, healthcare, and government agencies that deploy Snapdragon-based devices for communication, control, or monitoring purposes may face increased risk. The local privilege requirement limits remote exploitation but insider threats or compromised devices could be leveraged to exploit this flaw. Disruption or compromise of sensor data could affect operational technology environments and critical infrastructure, potentially causing cascading effects. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once patches are released. Therefore, European organizations must proactively address this vulnerability to prevent potential exploitation and operational impact.

1. Monitor Qualcomm and device vendors for official patches and apply them promptly once available to remediate the use-after-free vulnerability. 2. Restrict local high-privilege access to devices with affected Snapdragon chipsets to trusted personnel only, minimizing the risk of exploitation. 3. Implement strict access controls and auditing on systems that interact with sensor registers to detect and prevent unauthorized operations. 4. Employ runtime protections such as memory corruption mitigations (e.g., ASLR, DEP) where supported by the device firmware or operating system. 5. Conduct regular security assessments and penetration tests focusing on local privilege escalation vectors and sensor interface components. 6. Deploy endpoint detection and response (EDR) solutions capable of monitoring anomalous behavior related to sensor operations and memory corruption attempts. 7. Educate staff about the risks of local privilege misuse and enforce policies to reduce insider threat risks. 8. For critical infrastructure, consider network segmentation and isolation of devices with affected chipsets to limit attack surface. 9. Maintain up-to-date inventories of devices using Qualcomm Snapdragon components to prioritize remediation efforts effectively.
