CVE-2025-47339 is a use-after-free vulnerability classified under CWE-416, discovered in Qualcomm Snapdragon chipsets and platforms. The vulnerability arises during the deinitialization process of High-bandwidth Digital Content Protection (HDCP) sessions, where memory corruption occurs due to improper handling of freed memory. This flaw affects an extensive list of Qualcomm products, including various Snapdragon mobile platforms (e.g., Snapdragon 4 Gen 2, 6 Gen 1, 8 Gen 3), FastConnect wireless subsystems, Immersive Home platforms, IPQ series, QCA series, QCN series, and other specialized chipsets used in mobile, automotive, IoT, and networking devices. The CVSS v3.1 score is 7.8, indicating high severity, with the attack vector being local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H), meaning an attacker with local access could exploit the flaw to execute arbitrary code, escalate privileges, or cause denial of service. The vulnerability is currently published with no known exploits in the wild, but the broad attack surface and critical nature of HDCP session management make it a significant risk. Qualcomm and affected vendors need to issue patches, but no patch links are currently provided. The vulnerability's exploitation could compromise devices used in critical communication infrastructure, mobile endpoints, and automotive systems, potentially leading to data breaches, system instability, or control takeover.

For European organizations, the impact of CVE-2025-47339 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, enterprise networking equipment, IoT devices, and automotive systems. Confidentiality breaches could expose sensitive corporate or personal data, while integrity and availability impacts could disrupt critical services or enable persistent unauthorized access. Telecommunications providers and enterprises relying on mobile endpoints with affected Snapdragon platforms may face increased risk of targeted local attacks, especially in environments where physical or local network access is possible. Automotive manufacturers and suppliers using Snapdragon-based platforms in connected vehicles could experience safety and operational risks if attackers exploit this vulnerability. The lack of user interaction requirement and low complexity of exploitation increase the likelihood of successful attacks in environments where local access controls are weak. Given the critical role of HDCP in content protection, media and entertainment sectors could also be affected by content piracy or tampering. Overall, the vulnerability threatens multiple sectors, potentially causing operational disruptions, data loss, and reputational damage.

1. Immediate coordination with Qualcomm and device manufacturers to obtain and deploy security patches as soon as they become available is critical. 2. Implement strict local access controls and monitoring to limit the ability of attackers to gain the required local privileges for exploitation. 3. Employ runtime memory protection mechanisms such as Address Space Layout Randomization (ASLR) and Control Flow Integrity (CFI) where supported by the platform to reduce exploitation success. 4. Monitor HDCP session management logs and system behavior for anomalies indicative of exploitation attempts or memory corruption. 5. For enterprise and telecom environments, segment networks to isolate critical devices and reduce local attack surfaces. 6. Conduct regular security audits and vulnerability assessments on devices using affected Qualcomm chipsets. 7. Educate users and administrators about the risks of local privilege escalation and enforce strong endpoint security policies. 8. Consider deploying endpoint detection and response (EDR) solutions capable of detecting suspicious local activity related to memory corruption or privilege escalation. 9. For automotive and IoT deployments, ensure secure firmware update mechanisms are in place to facilitate timely patching. 10. Collaborate with vendors to receive timely vulnerability intelligence and updates.
