CVE-2026-31280Public exploit

Device crash via oversized unauthenticated RFCOMM payloads

Published Apr 13, 2026 · Updated Apr 13, 2026

Buffer overflow in the Bluetooth RFCOMM service of Parani M10 Motorcycle Intercom 2.1.3 allows physically proximate attackers to crash it. The RFCOMM handler accepts an oversized crafted payload without validating its length, overflowing a buffer until the intercom crashes or reboots. Bluetooth-range access is sufficient because the service permits direct channel connections without secure pairing or user interaction, and recovery requires manual intervention.
