Preface: Linux makes very efficient use of the system’s resources.You can give new life to your old and slow Windows system by installing a lightweight Linux system. Variants of Linux are most widely used in the Internet of things and smart devices.
Namespaced mapping – when the two sorted arrays are used, the new code omits the ID transformation for the kernel . Found design flaw in kernel that DAC security controls on files whose IDs aren’t mapped in namespace.
So, user who has CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace.
Comment: The Linux operating system is heavily used in modern computer equipment. Will it have an impact soon?
