CVE-2025-47358 is a use-after-free vulnerability categorized under CWE-416, affecting multiple Qualcomm Snapdragon platforms including FastConnect 6900 and 7800 modules, QCC2072, SC8380XP, Snapdragon 8cx Gen 3 Compute Platform variants, and several WCD and WSA series components. The root cause is a memory corruption issue triggered when a user space address is modified and subsequently passed to the mem_free API, which inadvertently frees kernel memory. This improper memory management can lead to kernel memory corruption, potentially allowing an attacker with limited privileges to execute arbitrary code in kernel context, escalate privileges, or cause denial of service through system crashes. The vulnerability requires local access with low privileges but does not require user interaction, increasing the risk in multi-user or shared device environments. The CVSS v3.1 score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates that the attack vector is local, with low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability at a high level. Although no exploits are currently known in the wild, the broad range of affected Snapdragon components, which are embedded in many mobile, IoT, and computing devices, makes this vulnerability a significant concern. The absence of patch links suggests that fixes may still be forthcoming, emphasizing the need for vigilance and proactive mitigation.

For European organizations, the impact of CVE-2025-47358 can be substantial, particularly for sectors relying heavily on Qualcomm Snapdragon-based devices such as telecommunications providers, mobile device manufacturers, IoT deployments, and enterprises using embedded computing platforms. Exploitation could lead to unauthorized kernel-level code execution, allowing attackers to bypass security controls, access sensitive data, disrupt services, or establish persistent footholds. This could compromise user privacy, intellectual property, and critical infrastructure operations. The vulnerability’s local attack vector means that insider threats or compromised user accounts could be leveraged to exploit the flaw. Given the widespread use of Snapdragon components in smartphones, tablets, laptops, and IoT devices, the attack surface is large. Disruption or compromise of these devices could affect business continuity, regulatory compliance (e.g., GDPR), and customer trust. The high severity underscores the urgency for European organizations to assess their exposure and implement mitigations promptly.

1. Monitor Qualcomm and device vendors for official patches and apply them immediately upon release to remediate the vulnerability. 2. Restrict local access to devices running affected Snapdragon components by enforcing strict user authentication and limiting administrative privileges to trusted personnel only. 3. Employ endpoint detection and response (EDR) solutions capable of monitoring kernel-level anomalies and suspicious memory operations indicative of exploitation attempts. 4. Harden device configurations by disabling unnecessary services and interfaces that could provide local access vectors. 5. Conduct regular security audits and penetration testing focusing on privilege escalation and memory corruption vulnerabilities. 6. For organizations deploying IoT or embedded devices, implement network segmentation to isolate vulnerable devices and reduce lateral movement risk. 7. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of maintaining updated firmware and software. 8. Maintain an inventory of devices using affected Snapdragon components to prioritize patching and risk management efforts.
