CVE-2025-47347
7.8Qualcomm · Snapdragon
A stack-based buffer overflow in the virtual memory management interface of certain Qualcomm Snapdragon processors allows for potential memory corruption when processing control commands.
Executive summary
A high-severity memory corruption vulnerability in Qualcomm Snapdragon processors poses a significant risk of local privilege escalation or system instability.
Vulnerability
This is a stack-based buffer overflow (CWE-121) occurring within the virtual memory management interface. Based on the CVSS vector (PR:L), successful exploitation requires an attacker to have already established low-level local access to the system.
Business impact
With a CVSS score of 7.8, this vulnerability is classified as High. An attacker capable of triggering this memory corruption could potentially escalate privileges, execute arbitrary code with elevated permissions, or cause a denial-of-service condition, leading to unauthorized system control or total service disruption.
Remediation
Immediate Action: Consult the official Qualcomm October 2025 security bulletin to identify specific firmware or driver updates for the affected Snapdragon chipsets and apply them as soon as they are made available by the device manufacturer.
Proactive Monitoring: Monitor system logs for unexpected crashes or service restarts in memory management components, which may indicate attempts to trigger the buffer overflow.
Compensating Controls: Ensure that systems are running with hardened kernel configurations and that user privileges are strictly limited to minimize the impact of a potential local exploitation attempt.
Exploitation status
Public Exploit Available: No
Analyst recommendation
Given the potential for complete compromise of the affected hardware, administrators should treat this vulnerability with high priority. Organizations using the specified Snapdragon chipsets must coordinate with their hardware vendors to obtain and deploy the necessary security patches as soon as they are released to prevent local privilege escalation.
