CVE-2025-47347 is a stack-based buffer overflow vulnerability classified under CWE-121, discovered in Qualcomm Snapdragon chipsets. The flaw occurs due to improper handling of control commands within the virtual memory management interface, leading to memory corruption. This vulnerability affects a wide range of Snapdragon models including QAM, QCA, SA, and SRV series chipsets widely deployed in mobile phones, IoT devices, and embedded systems. The CVSS v3.1 score of 7.8 indicates high severity, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this flaw could allow an attacker with local privileges to execute arbitrary code, escalate privileges, or cause denial of service by corrupting memory. Although no public exploits are reported yet, the vulnerability's nature and affected components suggest a significant risk if leveraged by attackers. The broad chipset coverage means many devices globally, including those used in Europe, could be vulnerable. Qualcomm has not yet released patches, so mitigation currently relies on limiting local access and monitoring. The vulnerability's presence in critical mobile and embedded platforms underscores the importance of rapid remediation once fixes are available.

For European organizations, the impact of CVE-2025-47347 is substantial due to the widespread use of affected Snapdragon chipsets in smartphones, tablets, and embedded devices. Successful exploitation can lead to unauthorized code execution, privilege escalation, and system crashes, compromising device security and potentially exposing sensitive corporate or personal data. This could disrupt business operations, especially in sectors relying heavily on mobile communications such as finance, healthcare, and government. The vulnerability also threatens the integrity of IoT deployments and critical infrastructure components that use these chipsets, increasing risks of sabotage or espionage. Given the local access requirement, insider threats or malware with initial foothold could leverage this flaw to deepen system compromise. The absence of patches increases exposure time, and the high confidentiality, integrity, and availability impact could lead to regulatory repercussions under GDPR if personal data is compromised. Hence, European entities must prioritize risk assessment and containment strategies for devices with vulnerable Snapdragon versions.

1. Monitor Qualcomm and device vendors closely for official patches and apply them immediately upon release. 2. Restrict local access to devices with affected Snapdragon chipsets by enforcing strict physical security and limiting administrative privileges. 3. Implement endpoint detection and response (EDR) solutions to identify anomalous behavior indicative of exploitation attempts, such as unusual memory access patterns or crashes. 4. Harden device configurations by disabling unnecessary services and interfaces that could be used to deliver local attacks. 5. Conduct regular security audits and penetration testing focusing on local privilege escalation vectors. 6. Educate users and administrators about the risks of local exploitation and the importance of not installing untrusted software. 7. For embedded or IoT devices, isolate vulnerable devices on segmented networks to reduce lateral movement opportunities. 8. Maintain up-to-date inventories of devices with affected chipsets to prioritize mitigation efforts effectively.
