CVE Alert: CVE-2025-47354 – Qualcomm, Inc. – Snapdragon

Risk verdict

High risk if exploited locally; the DSP service memory corruption could lead to complete device compromise, though there is no indication of active exploitation at this time.

Why this matters

Memory corruption in a trusted DSP component can expose confidential data, compromise integrity, or disrupt availability across affected devices. Because the flaw only requires local access with low privileges and no user interaction, an attacker with a foothold could progress to full control, potentially affecting enterprise and consumer devices alike.

Most likely attack path

An attacker with local access uses crafted data to trigger a use-after-free in the DSP service, leveraging low-privilege access to obtain code execution within the DSP context. From there, escalation to broader system control or data exposure is plausible if additional weaknesses or preconditions exist. No user interaction is required, and the impact vector is broad (C, I, A) with an unchanged scope.

Who is most exposed

Mobile and wearables in consumer and business environments relying on affected DSP services are at risk, especially devices with longstanding OS or vendor update cycles that may delay patching.

Detection ideas

• DSP service crashes or watchdog restarts linked to memory faults
• Anomalous kernel or system traces indicating use-after-free conditions
• Unusual memory allocator events or heap inconsistencies on device boot or idle periods
• Increased DSP-related fault counters or crash dumps in telemetry
• Vendor advisories or OVF logs referencing CVE-like signatures

Mitigation and prioritisation

• Apply vendor/OS updates as soon as available; coordinate with OEMs for device-wide patches
• Restrict exposure where feasible; ensure least-privilege IPC paths to DSP service
• Enable strong memory protection and exploit mitigations (ASLR, DEP, sandboxing)
• Monitor for DSP-service crashes and targeted exploitation indicators; collect crash analytics
• Change-management note: plan a staged rollout, prioritising high‑risk devices; document patch status and recovery options
• If explicit exploitation indicators emerge or EPSS/KEV signals update to higher priority, escalate to priority 1
