CVE-2026-25271
Qualcomm · Snapdragon
A race condition in Qualcomm Snapdragon components allows memory corruption due to improper handling of parameters between check and use.
Executive summary
A high-severity race condition vulnerability in Qualcomm Snapdragon firmware could enable local authenticated attackers to achieve memory corruption and potentially execute arbitrary code.
Vulnerability
This is a Time-of-check Time-of-use (TOCTOU) race condition (CWE-367) that occurs when processing asynchronous input parameters, requiring local authenticated access to exploit.
Business impact
With a CVSS score of 7.8, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of the affected system. Exploitation could lead to unauthorized code execution at the firmware level, resulting in permanent data compromise or total system failure.
Remediation
Immediate Action: Review the July 2026 Qualcomm security bulletin and apply the relevant firmware updates from the hardware vendor.
Proactive Monitoring: Review system performance logs for evidence of race condition artifacts or unexpected service restarts.
Compensating Controls: Restrict local access to the device and ensure that all firmware-level security features are active to limit the attack surface.
Exploitation status
Public Exploit Available: false
Analyst recommendation
Firmware vulnerabilities of this nature are difficult to detect and remediate without vendor intervention. Prioritize the deployment of manufacturer-supplied updates to neutralize this TOCTOU race condition and secure the underlying hardware components.
