CVE-2025-47396 is a double free vulnerability classified under CWE-415 found in multiple Qualcomm Snapdragon platforms and associated wireless connectivity products. The vulnerability arises when a secure application is launched on a device that lacks sufficient memory, leading to memory corruption due to improper handling of memory deallocation. Double free vulnerabilities occur when the same memory location is freed more than once, which can corrupt the memory management data structures, potentially allowing an attacker to execute arbitrary code, escalate privileges, or cause denial of service. The affected products include a broad range of Snapdragon chipsets such as FastConnect 6200 through 7800 series, Snapdragon 4 Gen 2, 6 Gen 1 Mobile Platforms, AR1 Gen 1 Platforms, wearable platforms like Snapdragon W5+ Gen 1, and various wireless connectivity modules (WCD, WCN, WSA series). The CVSS v3.1 base score is 7.8, reflecting high severity with attack vector local (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits are known at this time, but the vulnerability poses a significant risk due to the widespread deployment of affected Snapdragon platforms in mobile devices, wearables, and IoT devices. The flaw could be exploited by an attacker with local access to the device to corrupt memory, potentially leading to privilege escalation or denial of service in secure environments.

For European organizations, the impact of CVE-2025-47396 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, tablets, wearables, and IoT devices. Confidentiality could be compromised if attackers exploit the memory corruption to access sensitive data processed by secure applications. Integrity and availability are also at risk, as attackers could manipulate or crash critical secure processes, potentially disrupting business operations or device functionality. Industries relying heavily on mobile and IoT technologies, such as telecommunications, finance, healthcare, and manufacturing, could face operational disruptions or data breaches. The local attack vector means that physical or local network access is required, which may limit remote exploitation but does not eliminate risk in environments where devices are shared or accessible. The lack of user interaction requirement increases the risk of stealthy exploitation. The absence of known exploits in the wild currently reduces immediate threat but does not preclude future attacks, especially as threat actors analyze the vulnerability. The broad range of affected Snapdragon platforms means a large attack surface across consumer and enterprise devices in Europe.

European organizations should implement a multi-layered mitigation strategy. First, monitor Qualcomm and device manufacturers for official patches or firmware updates addressing CVE-2025-47396 and deploy them promptly. Until patches are available, restrict local access to devices running affected Snapdragon platforms, especially in sensitive or high-security environments. Employ strict physical security controls and endpoint protection to prevent unauthorized local access. Use application whitelisting and sandboxing to limit the execution of untrusted or unnecessary secure applications that could trigger the vulnerability. Conduct regular memory and process integrity monitoring to detect anomalous behavior indicative of exploitation attempts. For device manufacturers and developers, review and improve memory management routines in secure applications to prevent double free conditions, including rigorous testing under low-memory conditions. Additionally, implement runtime protections such as Address Space Layout Randomization (ASLR) and Control Flow Integrity (CFI) to mitigate exploitation impact. Finally, raise user and administrator awareness about the risks of local attacks and the importance of device security hygiene.
