Apple Mac OS is on top for having highest number of vulnerabilities in 2015!

With the highest number of vulnerabilities in 2015, Apple Mac OS X software is on the top. Apple Mac OS got this rank according to the data which has been provided by CVE Details.

If anyone ask which software had the highest number of vulnerabilities in 2015, which were publicly disclosed by the researchers then its answer is Apple Mac OS X. According to the CVE Details there were 384 major vulnerabilities in Mac OS X which had been disclosed by the experts.  After that Apple iOS is at number two with 375 vulnerabilities. With 314 vulnerabilities Adobe flash player is at number three.

This has been decided by CVE Details. CVE Details manages all the data which NVD (National Vulnerability Database) provide to them. All the vulnerabilities which are publicly disclosed have been track by the Common Vulnerability Exposures system of NVD.

These results are very surprising as compare to the results of 2014. In 2014, Microsoft’s Internet Explorer was on top. MAC OS X was at number two. After that there was Linux kernel and then then Google Chrome in the list. So here the point to be noticed is that Microsoft, Linux Kernel and Google chrome have done a shocking improvement in their security techniques. Various versions of windows have been reported in the top 50 charts. There are a number of cases in which same flaw affect the multiple version of Windows OS. This is not a good thing for windows. All the other OSs are not split into separate versions and Mac OS X, iOS and Android OS are included in these Oss.

According to a report of VentureBeat,” The argument for separating them is probably one of market share, though that’s a hard one to agree to, given that Android and iOS are not split into separate versions. This is the nature of CVEs.”

Now if we talk about the top vulnerabilities affected application vendors, which have been disclosed in 2025, then Microsoft is at top with 1561 vulnerabilities, Adobe is at number two with 1504 vulnerabilities and Apple is at number three with 1147 vulnerabilities.

All the above ranking is according to the vulnerabilities which are publicly disclosed by experts and researchers but there are a number of vulnerabilities which had not been reported by the researchers. One more thing, this data is not related to the data of cyber-attacks which had been performed by hackers. In that case we can say JAVA based software’s and Adobe applications are on top. Because most of the attacks had been performed by attackers by exploiting JAVA and Adobe based applications.
