Zephyrproject: >> Zephyr Security Vulnerabilities
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.

Multiple syscalls in the Kscan subsystem perform insufficient argument validation, allowing code executing in userspace to potentially gain elevated privileges. See NCC-ZEP-006 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions.

The UpdateHub module disables DTLS peer checking, which allows for a man in the middle attack. This is mitigated by firmware images requiring valid signatures. However, there is no benefit to using DTLS without the peer checking. See NCC-ZEP-018 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions.

zephyr-rtos version 1.12.0 contains a NULL base pointer reference vulnerability in sys_ring_buf_put(), sys_ring_buf_get() that can result in CPU Page Fault (error code 0x00000010). This attack appear to be exploitable via a malicious application call the vulnerable kernel APIs (system sys_ring_buf_get() and sys_ring_buf_put).
