CVE-2025-47393 is a vulnerability identified in the kernel driver of Qualcomm Snapdragon chipsets, specifically caused by improper validation of array indices (CWE-129). This flaw leads to memory corruption when the driver accesses resources, which can be exploited by a local attacker with limited privileges to manipulate memory, potentially resulting in arbitrary code execution, privilege escalation, or denial of service. The vulnerability affects a broad range of Snapdragon models, including QAM8255P, QAM8650P, SA9000P, and others, which are commonly integrated into mobile devices, IoT devices, and embedded systems. The CVSS v3.1 score of 7.8 reflects a high severity due to the vulnerability’s impact on confidentiality, integrity, and availability, combined with low attack complexity and no requirement for user interaction. Although no public exploits are currently known, the vulnerability’s presence in widely deployed hardware makes it a significant concern. The root cause is the failure to properly validate array indices before accessing memory, which can lead to out-of-bounds reads or writes in kernel space. This can corrupt memory structures, allowing attackers to execute arbitrary code with kernel privileges or crash the system. The vulnerability was reserved in May 2025 and published in January 2026, but Qualcomm has not yet released patches, emphasizing the need for vigilance and interim mitigations.

For European organizations, the impact of CVE-2025-47393 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in smartphones, telecommunications equipment, and embedded systems critical to infrastructure. Exploitation could lead to unauthorized access to sensitive data, disruption of services, and compromise of device integrity. Telecommunications providers, government agencies, and enterprises relying on Snapdragon-powered devices for secure communications or operational technology could face data breaches or service outages. The vulnerability’s ability to escalate privileges locally means that insider threats or malware already present on a device could leverage this flaw to gain full control, increasing the risk of lateral movement and persistent compromise. Additionally, denial of service attacks could disrupt critical services, impacting business continuity. The lack of user interaction requirement and low attack complexity further increase the risk profile. Organizations in sectors such as finance, healthcare, and critical infrastructure in Europe must consider this vulnerability a priority due to potential cascading effects on confidentiality, integrity, and availability.

1. Monitor Qualcomm’s advisories closely and apply official patches immediately upon release to remediate the vulnerability at the kernel driver level. 2. Until patches are available, restrict local access to devices using affected Snapdragon chipsets by enforcing strong physical security and limiting user privileges to trusted personnel only. 3. Implement endpoint detection and response (EDR) solutions capable of detecting anomalous kernel-level activity indicative of exploitation attempts. 4. Employ strict application whitelisting and sandboxing on devices to reduce the risk of malicious code execution leveraging this vulnerability. 5. Conduct regular security audits and vulnerability assessments on Snapdragon-based devices within the organization to identify potential exposure. 6. For embedded and IoT devices, consider network segmentation and isolation to limit the impact of a compromised device. 7. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of maintaining updated device firmware and software. 8. Collaborate with device manufacturers and service providers to ensure timely updates and coordinated vulnerability management.
