RIOT OS 安全漏洞

RIOT OS is an IoT operating system from RIOT Open Source. A security vulnerability exists in RIOT OS version 2026.01-devel-317 and earlier, which stems from a lack of boundary checking when the ethos tool handles serial frame data, which could lead to memory corruption and application crashes...

CVE-2021-41061

In RIOT-OS 2021.01, nonce reuse in 802.15.4 encryption in the ieee820154security component allows attackers to break encryption by triggering reboots...

CVE-2021-27697

RIOT-OS 2021.01 contains a buffer overflow vulnerability in sys/net/gnrc/routing/rpl/gnrcrplvalidation.c through the gnrcrplvalidationoptions function...

CVE-2021-27427

RIOT OS version 2020.01.1 is vulnerable to integer wrap-around in its implementation of calloc function, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution...

CVE-2019-16754

RIOT 2019.07 contains a NULL pointer dereference in the MQTT-SN implementation asymcute, potentially allowing an attacker to crash a network node running RIOT. This requires spoofing an MQTT server response. To do so, the attacker needs to know the MQTT MsgID of a pending MQTT protocol message an...
