CVE-2025-47378

7.1

Qualcomm, Inc. · Snapdragon

A cryptographic vulnerability in Qualcomm Snapdragon products allows a shared VM reference to expose the certificate chain to the High Level Operating System during the boot loader process.

Executive summary

A vulnerability in Qualcomm Snapdragon chipsets allows for the unauthorized exposure of sensitive cryptographic information, posing a significant risk to device integrity.

Vulnerability

This issue is classified as an exposure of sensitive system information (CWE-497), where a shared VM reference permits the High Level Operating System to access the boot loader and its associated certificate chain, requiring local low-privileged access.

Business impact

The compromise of the certificate chain can lead to a total loss of trust in the device boot process, potentially allowing for the execution of unauthorized or malicious firmware. Given the CVSS score of 7.1, this is a high-severity flaw that could result in persistent device compromise, data exfiltration, and a complete breakdown of secure boot mechanisms within the affected hardware ecosystem.

Remediation

Immediate Action: Consult the official Qualcomm March 2026 security bulletin to identify specific firmware update packages for the impacted chipset models and apply them as soon as they are made available by the device manufacturer.

Proactive Monitoring: Monitor system logs for unauthorized attempts to interact with low-level boot processes or unexpected modifications to secure storage regions.

Compensating Controls: Ensure that device integrity checks and remote attestation services are enabled to detect potential unauthorized changes to the boot loader environment.

Exploitation status

Public Exploit Available: No — there is no confirmed public exploit available.

Analyst recommendation

Due to the high-severity nature of this cryptographic exposure, organizations utilizing affected Qualcomm hardware should prioritize the deployment of firmware updates provided by their original equipment manufacturer. Failure to patch this vulnerability could expose devices to persistent, low-level threats that bypass standard OS-level security controls.
