Vulnerability Title
Integer Overflow In is_in_region Allows User Thread To Access Kernel Memory
Source: NVD (National Vulnerability Database)
Vulnerability Description
A malicious userspace application can cause a integer overflow and bypass security checks performed by system call handlers. The impact would depend on the underlying system call and can range from denial of service to information leak to memory corruption resulting in code execution within the kernel. See NCC-ZEP-005 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions.
