CVE-2025-21422: CWE-310 Cryptographic Issues in Qualcomm, Inc. Snapdragon
Cryptographic issue while processing crypto API calls, missing checks may lead to corrupted key usage or IV reuses.
AI Analysis
Technical Summary
CVE-2025-21422 is a cryptographic vulnerability affecting a wide range of Qualcomm Snapdragon platforms and associated wireless connectivity modules. The issue stems from improper handling of cryptographic API calls, specifically missing validation checks that can lead to corrupted key usage or reuse of initialization vectors (IVs). IV reuse and corrupted keys undermine the fundamental security guarantees of cryptographic operations, potentially allowing attackers to decrypt sensitive data, forge messages, or bypass encryption protections. The vulnerability impacts numerous Snapdragon mobile platforms, compute platforms, modem-RF systems, and wireless connectivity chips, spanning generations from older Snapdragon 845 to the latest Snapdragon 8 Gen 3 and various specialized platforms such as AR, robotics, and video collaboration. The CVSS v3.1 score of 7.1 (high severity) reflects the vulnerability's significant confidentiality and integrity impact, requiring local privileges with low complexity and no user interaction. Exploitation does not affect availability. Although no known exploits are currently reported in the wild, the breadth of affected devices and the critical role of cryptographic operations in securing communications and data storage make this a serious concern. The vulnerability could be exploited by malicious applications or privileged processes on affected devices to compromise cryptographic protections, leading to data leakage or unauthorized data manipulation. The lack of available patches at the time of publication further elevates risk for users and organizations relying on vulnerable Snapdragon hardware.
Potential Impact
For European organizations, the impact of CVE-2025-21422 is substantial due to the widespread use of Qualcomm Snapdragon chipsets in mobile devices, IoT equipment, and embedded systems. Confidentiality breaches could expose sensitive corporate communications, intellectual property, and personal data protected by encryption. Integrity violations could allow attackers to tamper with data or authentication tokens, potentially enabling privilege escalation or fraud. The vulnerability's local attack vector means that malware or insider threats with limited access could exploit this flaw to escalate their capabilities. This is particularly concerning for sectors with high mobile device usage such as finance, healthcare, and government. Additionally, embedded Snapdragon platforms in industrial IoT or robotics could face operational risks if cryptographic protections fail, potentially disrupting critical infrastructure or manufacturing processes. The absence of known exploits currently provides a window for mitigation, but the high severity and broad device impact necessitate urgent attention to prevent future attacks. Organizations relying on Snapdragon-based devices should assess their exposure, especially for devices used in sensitive roles or handling regulated data under GDPR and other European privacy laws.
Mitigation Recommendations
Mitigation should focus on a multi-layered approach: 1) Immediate inventory and identification of all devices and embedded systems using affected Qualcomm Snapdragon platforms within the organization. 2) Monitor Qualcomm and device vendors for official patches or firmware updates addressing CVE-2025-21422 and apply them promptly once available. 3) Implement strict application whitelisting and privilege management to limit local code execution capabilities, reducing the risk of local exploitation. 4) Employ runtime application self-protection (RASP) and endpoint detection and response (EDR) solutions to detect anomalous cryptographic API usage or suspicious local activity. 5) For critical systems, consider network segmentation and enhanced monitoring of device communications to detect potential data exfiltration or manipulation. 6) Engage with device manufacturers and suppliers to confirm patch timelines and request interim mitigations or workarounds. 7) Educate users and administrators about the risks of installing untrusted applications or granting elevated privileges on affected devices. 8) For embedded or IoT devices where patching is delayed or unavailable, evaluate compensating controls such as disabling vulnerable features or isolating devices from sensitive networks. These targeted measures go beyond generic advice by focusing on the unique local attack vector and cryptographic nature of the vulnerability.
