HighCVSS 8.7
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Low risk
0.16%

5th percentile - higher than 5% of all known CVEs

Summary

A buffer overflow in the Bluetooth Continuous Glucose Monitoring Service (CGMS) Record Access Control Point (RACP) write handler allows an authenticated BLE peer to overflow a 20-byte static buffer into adjacent BSS memory. The exploitable impact cannot be predetermined and depends on the linker-assigned BSS layout of the specific firmware build.

Risk Assessment

Risk of potential code execution or memory integrity compromise, potentially leading to unauthorized actions on medical devices.

Recommendation

Apply firmware vendor patches that fix the buffer overflow and restrict trusted BLE peers.

Original NVD description (English source)

A buffer overflow in the Bluetooth Continuous Glucose Monitoring Service (CGMS) Record Access Control Point (RACP) write handler allows an authenticated BLE peer to overflow a 20-byte static buffer into adjacent BSS memory. The exploitable impact cannot be predetermined - it is entirely dependent on the linker-assigned BSS layout of the specific firmware build, which may vary.
