Short explanation
CVE-2025-66367 allows an out-of-bounds read in Samsung Semiconductor’s Exynos series when NAS DLTransport messages are mishandled, potentially causing a baseband crash.
A baseband crash can render the device’s communication functions inoperable, leading to denial of service.
What should be done?
- Monitor Samsung’s security advisory page for updates
- Apply firmware patches when released
- Restrict untrusted NAS traffic where feasible
- Conduct baseband firmware testing
- Deploy monitoring/IDS for abnormal baseband behavior
