CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10024 – ARM Platform Uses Signed Integer Comparison When Validating Syscall Numbers
https://notcve.org/view.php?id=CVE-2020-10024
The arm platform-specific code uses a signed integer comparison when validating system call numbers. An attacker who has obtained code execution within a user thread is able to elevate privileges to that of the kernel. See NCC-ZEP-001 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions. El código arm específico de la plataforma utiliza una comparación de enteros con signo cuando se comprueban los números de llamada del sistema. Un atacante que ha obtenido una ejecución de código dentro de un subproceso (hilo) de usuario es capaz de elevar los privilegios a los del kernel. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10024 https://github.com/zephyrproject-rtos/zephyr/pull/23323 https://github.com/zephyrproject-rtos/zephyr/pull/23498 https://github.com/zephyrproject-rtos/zephyr/pull/23535 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-30 • CWE-697: Incorrect Comparison •
CVSS: 6.9EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10023 – Shell Subsystem Contains a Buffer Overflow Vulnerability In shell_spaces_trim
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.

CVSS: 9.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10022 – UpdateHub Module Copies a Variable-Size Hash String Into a Fixed-Size Array
https://notcve.org/view.php?id=CVE-2020-10022
A malformed JSON payload that is received from an UpdateHub server may trigger memory corruption in the Zephyr OS. This could result in a denial of service in the best case, or code execution in the worst case. See NCC-NCC-016 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. version 2.2.0 and later versions. Una carga útil JSON malformada que es recibida desde un servidor UpdateHub puede desencadenar una corrupción de la memoria en el Sistema Operativo Zephyr.
