CVE-2026-14297

HIGHCVSS 8.7/10EPSS 0.15%

Last modified

CVE-2026-14297 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
