CVE-2026-14297 – A buffer overflow in the Bluetooth Continuous Glucose Monitoring Service (CGMS) Recor

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.
