According to analysis from the National Institute of Standards and Technology’s National Vulnerability Database has shown that Android had the most vulnerabilities is any indication of exploitability, than Windows 10, Mac OS or Linux.
Android is the most popular mobile platform and, as a result, the most vulnerable. Its market share is a record high, and developers and attackers are trying to create malware that allows hacking devices.
Over the last decade, Debian Linux had 3067 technical vulnerabilities, next was Android with 2563, the Linux kernel with 2357 and Mac OSX with 2212.Windows 10 only recorded 1111 technical vulnerabilities, and even if we add Windows 10 (released in 2015) to Windows 7 (released in 2009), the total is still much less than Android and Debian Linux.
It is worth mentioning that Google has recently corrected 71 Android security flaws in its March 2020 patch.
