CVE-2025-47377 is a use-after-free vulnerability classified under CWE-416, discovered in Qualcomm Snapdragon chipsets and platforms. The vulnerability occurs due to improper handling of memory buffers during IOCTL (Input/Output Control) call processing, where a buffer is accessed after it has been freed, leading to memory corruption. This flaw can be exploited by a local attacker with limited privileges (PR:L) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H) of the affected systems, as an attacker could execute arbitrary code, escalate privileges, or cause system crashes. The affected products span a broad range of Qualcomm Snapdragon platforms including mobile processors (e.g., Snapdragon 8 Gen 2, Snapdragon 695 5G), connectivity modules (FastConnect series), automotive platforms (Flight RB5 5G, Robotics RB5), wearable platforms (Snapdragon W5+), and modem-RF systems (Snapdragon X series). The CVSS v3.1 base score is 7.8, indicating high severity. The vulnerability was published on March 2, 2026, with no known exploits in the wild and no patches currently available. Due to the extensive list of affected hardware, the vulnerability poses a significant risk to devices relying on Qualcomm Snapdragon components for critical operations. The flaw requires local access, which limits remote exploitation but still presents a serious threat in scenarios where attackers gain initial foothold or insider access. The vulnerability's exploitation could lead to privilege escalation, arbitrary code execution, and denial of service, severely impacting device security and user data privacy.

The impact of CVE-2025-47377 is substantial for organizations worldwide that deploy devices and systems based on Qualcomm Snapdragon platforms. Successful exploitation can lead to complete compromise of affected devices, including unauthorized access to sensitive data, disruption of critical services, and persistent control by attackers. This is particularly concerning for mobile devices, automotive systems, IoT devices, and wearables that rely on these chipsets for secure operation. Enterprises using Snapdragon-based devices for communication, data processing, or operational technology may face data breaches, operational downtime, and reputational damage. The vulnerability's local exploit requirement means attackers need some level of access, but this can be achieved through other attack vectors such as phishing, malware, or insider threats. The broad range of affected platforms increases the attack surface, making it a critical concern for device manufacturers, service providers, and end users. The absence of known exploits currently provides a window for proactive mitigation, but the lack of patches necessitates immediate risk management to prevent exploitation once weaponized.

1. Restrict local access to devices and systems running affected Qualcomm Snapdragon platforms by enforcing strict access controls and monitoring for unauthorized privilege escalation attempts. 2. Employ application whitelisting and endpoint protection solutions to detect and prevent malicious activities that could lead to exploitation of the vulnerability. 3. Use secure boot and hardware-backed security features available on Snapdragon platforms to limit the impact of memory corruption exploits. 4. Implement rigorous input validation and sanitization for IOCTL calls and other interfaces that interact with kernel or driver components to reduce the risk of triggering use-after-free conditions. 5. Monitor vendor advisories closely for official patches or firmware updates addressing CVE-2025-47377 and plan timely deployment once available. 6. Conduct regular security audits and penetration testing focusing on privilege escalation and memory corruption vulnerabilities in Snapdragon-based devices. 7. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of maintaining device security hygiene. 8. Consider network segmentation and limiting exposure of critical devices to reduce the likelihood of attackers gaining local access necessary for exploitation.
