https://notcve.org/view.php?id=CVE-2020-10023
The shell subsystem contains a buffer overflow, whereby an adversary with physical access to the device is able to cause a memory corruption, resulting in denial of service or possibly code execution within the Zephyr kernel. See NCC-NCC-019 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions. El subsistema shell contiene un desbordamiento de búfer, por lo que un adversario con acceso físico al dispositivo es capaz de causar una corrupción de la memoria, resultando en una denegación de servicio o posiblemente en una ejecución de código dentro del kernel de Zephyr. Consulte NCC-NCC-019. Este problema afecta a: zephyrproject-rtos zephyr versión 1.14.0 y versiones posteriores. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10023 https://github.com/zephyrproject-rtos/zephyr/pull/23304 https://github.com/zephyrproject-rtos/zephyr/pull/23646 https://github.com/zephyrproject-rtos/zephyr/pull/23649 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-29 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

CVSS: 8.1EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10019 – Buffer Overflow in USB DFU requested length
https://notcve.org/view.php?id=CVE-2020-10019
USB DFU has a potential buffer overflow where the requested length (wLength) is not checked against the buffer size. This could be used by a malicious USB host to exploit the buffer overflow. See NCC-ZEP-002 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions. USB DFU presenta un potencial desbordamiento del búfer donde la longitud requerida (wLength) no es comparada con el tamaño del búfer. Esto podría ser usado por un host USB malicioso para explotar el desbordamiento del búfer. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10019 https://github.com/zephyrproject-rtos/zephyr/pull/23190 https://github.com/zephyrproject-rtos/zephyr/pull/23457 https://github.com/zephyrproject-rtos/zephyr/pull/23460 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-25 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
