CVE-2025-47340
7.8Qualcomm · Snapdragon (Various Components)
A memory corruption vulnerability exists in multiple Qualcomm Snapdragon components, stemming from improper handling of IOCTL calls used to retrieve mapping information.
Executive summary
A critical memory corruption vulnerability in various Qualcomm Snapdragon components poses a significant risk of local privilege escalation and system compromise.
Vulnerability
The flaw is an out-of-bounds write (CWE-787) triggered during the processing of IOCTL calls. The attack requires local access with low privileges to execute, potentially allowing for arbitrary code execution or system instability.
Business impact
The vulnerability carries a CVSS score of 7.8, indicating a high severity level. Successful exploitation allows a local attacker to escalate privileges or cause system crashes, potentially leading to unauthorized data access or total service disruption on affected mobile and computing devices.
Remediation
Immediate Action: Consult the official Qualcomm security bulletin for October 2025 to identify and apply the specific firmware or driver updates provided by the device manufacturer.
Proactive Monitoring: Monitor system logs for unusual IOCTL error patterns or unauthorized process execution attempts that may indicate exploitation of kernel-level interfaces.
Compensating Controls: Ensure that device security policies restrict the execution of untrusted local applications, as the attack vector requires local access to the system.
Exploitation status
Public Exploit Available: Unknown
Analyst recommendation
Given the high CVSS score and the nature of memory corruption vulnerabilities, organizations should prioritize the deployment of firmware updates provided by their device vendors. Security teams must treat this as a high-priority item to prevent potential privilege escalation within the device ecosystem.
