Vulnerability from variot

A buffer overflow in os/net/mac/ble/ble-l2cap.c in the BLE stack in Contiki-NG 4.4 and earlier allows an attacker to execute arbitrary code via malicious L2CAP frames. Contiki-NG Exists in a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Contiki-NG is an open source cross-platform operating system for next-generation IoT (Internet of Things) devices. There is a security vulnerability in os/net/mac/ble/ble-l2cap.c in the ble stack of Contiki-NG 4.4 and earlier versions
