With no known public exploits or confirmed exploitation, organizations still face real-world risks due to the potential for future attacks. Organizations should prioritize patching immediately.
The vulnerability was published on May 4, 2026. Organizations must take proactive measures to safeguard their environments against potential exploitation.
Vulnerability Details
The official description of CVE-2025-47408 states: 'Memory corruption when another driver calls an IOCTL with invalid input/output buffer.' The vulnerability is classified as memory corruption, which is critical for maintaining system integrity.
The CVSS score of 7.8 categorizes this vulnerability as high severity, indicating serious implications for affected systems. The attack vector is local, and the attack complexity is low, with required privileges also being low. Notably, there is no user interaction needed for exploitation.
The impact on confidentiality, integrity, and availability is rated as high, underscoring the need for organizations to take immediate action.
Technical Analysis
The root cause of this vulnerability stems from improper validation of input/output buffers in IOCTL calls, leading to memory corruption. The attack vector is local, meaning that an attacker must have local access to the system to exploit this vulnerability.
The attack complexity is low, as an attacker does not need advanced skills to exploit the vulnerability. Privileges required for exploitation are low, which means that a user with minimal access could potentially exploit the vulnerability. Importantly, no user interaction is required, increasing the risk of exploitation.
The vulnerability has a high impact on confidentiality, integrity, and availability, posing a significant threat to affected systems.
Risk & Impact Analysis
The potential real-world deployment risk associated with CVE-2025-47408 is significant, particularly for organizations relying on Qualcomm firmware such as FastConnect and Snapdragon components. The vulnerability allows local attackers to exploit memory corruption, which could lead to unauthorized access and disruption of services.
The urgency assessment is high, given the CVSS score and the potential for exploitation. Organizations must consider the blast radius potential, as successful exploitation could compromise the confidentiality and integrity of sensitive data, affecting both the organization and its customers.
Organizations should address this vulnerability in their priority patch cycle to mitigate associated risks effectively.
