Why this matters
Most likely attack path
Who is most exposed
Detection ideas
- DSP service crashes, kernel panics, or memory-related dumps.
- Abnormal memory/heap usage in DSP processing components.
- Logs showing failed or crafted user-buffer handling in the DSP subsystem.
- Unusual crash signatures or stack traces referencing DSP or memory corruption.
- Indicators in telemetry of attempted crafted inputs to the DSP path.
Mitigation and prioritisation
- Apply vendor security bulletin patches and firmware/OS updates as they become available.
- Enforce strict local-access controls; limit physical and peripheral access to affected devices.
- Deploy device-intake change control for timely firmware updates; test patches in a staging environment before enterprise rollout.
- Consider compensating controls where patching is slow (e.g., disable or sandbox DSP features where feasible, network/device segmentation).
- Reassess priority if KEV or EPSS data indicate higher exploitation likelihood.
