CVE Alert: CVE-2025-27032 – Qualcomm, Inc. – Snapdragon
CVE-2025-27032
memory corruption while loading a PIL authenticated VM, when authenticated VM image is loaded without maintaining cache coherency.
AI Summary Analysis
Risk verdict
High risk: local attacker could trigger memory corruption in the hypervisor by loading an authenticated VM image without cache coherency; no evidence of active exploitation in this dataset.
Why this matters
The issue permits fundamental breaches of confidentiality, integrity and availability at the hypervisor level. With low-privilege, local access, an attacker could potentially escape to the host or threaten other VMs, impacting enterprise devices and vehicles relying on Qualcomm’s Snapdragon platforms.
Most likely attack path
Exploitation requires local access (AV:L) with low pre-existing privileges (PR:L) and no user interaction (UI:N). The unchanged scope means exploitation could compromise the hypervisor or neighbouring VMs without needing to breach the host’s trust boundary. A successful path enables memory corruption, potentially enabling code execution or VM isolation bypass.
Who is most exposed
Devices deploying Snapdragon-based hypervisor/VM capabilities—mobile, automotive, industrial IoT, and embedded systems—are at greatest risk, particularly where authenticated VM images are loaded dynamically without strict cache coherency checks.
Detection ideas
- Hypervisor crash logs or kernel traces indicating memory corruption during VM image load.
- Anomalous VM image load sequences lacking cache coherency validation.
- Memory access异常 patterns or page-table/aliasing warnings in hypervisor logs.
- Unusual VM-to-VM or host access events following VM image loading.
- Firmware/hypervisor build diffs following the September 2025 bulletin.
Mitigation and prioritisation
- Apply the latest Qualcomm security bulletin and vendor patches to all affected platforms.
- Enforce strict cache coherency checks during VM image loading; block unauthenticated or non-compliant images.
- Limit local access to devices with hypervisor exposure; implement least-privilege controls.
- Validate and harden the hypervisor and memory management components; enable integrity monitoring and tamper detection.
- Update change-management plans and perform staged patches across fleets; if KEV is true or EPSS ≥ 0.5, treat as priority 1.
