CVE-2025-27038 Qualcomm CVE debrief

Who should care

Security teams, fleet managers, OEMs, and organizations using Qualcomm-based devices or products should care, especially where chipset exposure is hard to inventory. Teams responsible for patch management, device firmware, and third-party hardware advisories should verify whether any deployed products are affected and whether vendor mitigations are available.

Technical summary

The official source set identifies the issue as a use-after-free vulnerability affecting multiple Qualcomm chipsets. No additional specifics were provided in the supplied corpus about affected versions, attack surface, privileges required, or impact. CISA’s KEV entry directs users to apply vendor mitigations, consult applicable cloud guidance where relevant, or discontinue use if mitigations are unavailable.

Defensive priority

High priority. The CVE is listed in CISA’s KEV catalog, which indicates known exploitation and makes timely remediation important. The practical first step is to identify Qualcomm-dependent assets, then confirm patch or mitigation status through Qualcomm and the relevant OEM.

Recommended defensive actions

• Inventory devices, firmware, and products that depend on Qualcomm chipsets and determine whether they are exposed to CVE-2025-27038.
• Check Qualcomm’s June 2025 security bulletin and the relevant OEM advisories for patch availability and mitigation guidance.
• Apply vendor-recommended mitigations or updates as soon as they are available.
• If mitigations are not available, follow CISA’s guidance and discontinue use of the affected product where feasible.
• For cloud services or managed environments, follow applicable CISA BOD 22-01 guidance.
• Verify remediation before the CISA KEV due date of 2025-06-24 for systems in scope.
