CVE-2026-14297

The Continuous Glucose Monitoring Service's Record Access Control Point (RACP) write handler `memcpy`s the entire attacker-supplied ATT write value into a fixed 20-byte BSS buffer. PUBLISHED

Description (CNA)

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.
