CVE-2026-14297: Nordic Semiconductor ASA Nrf Connect SDK

High severity, CVSS 8.7. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Nordic Semiconductor ASA Nrf Connect SDK: from 2.2.0, up to and including 3.3.0
