Qualcomm Cologne Firmware
Raw vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:NSummary
CVE-2025-47378 is a high-severity Exposure of Sensitive System Information to an Unauthorized Control Sphere (CWE-497) vulnerability in Qualcomm Cologne Firmware. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique System Information Discovery (T1082); ranked at the 0.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-47378 is a cryptographic vulnerability stemming from a shared virtual machine (VM) reference that enables the High-Level Operating System (HLOS) to access the bootloader and certificate chain. It affects Qualcomm components, as detailed in their security advisories, and is classified under CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere). The issue received a CVSS v3.1 base score of 7.1 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to its potential for unauthorized access to sensitive cryptographic elements.
A local attacker with low privileges can exploit this vulnerability through low-complexity means without requiring user interaction. Successful exploitation allows high-impact confidentiality and integrity violations, such as reading sensitive certificate chain data or tampering with boot processes, while availability remains unaffected due to the unchanged scope.
Qualcomm's March 2026 security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/march-2026-bulletin.html provides further details on affected products, patches, and mitigation recommendations for this CVE.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.
Enforces information flow policies that block sensitive system data from crossing into unauthorized control spheres.
Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.
Controls communications at external and key internal boundaries to keep sensitive system information inside authorized spheres.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege access permissions directly prevents unauthorized actors from reaching sensitive system information.
Protecting environments from unauthorized logical access stops exposure of internal system details to outsiders.
Secure-development practices reduce the chance of code paths that leak sensitive system information.
