Many of the bugs added this year were many years old.
There was a slight reduction in the number of known exploited vulnerabilities in 2024 from those recorded by CISA in its catalog.
The number reached 185 this year, compared with 187 in 2023. This brings the total of flaws added by the agency since the catalog's inception over two years ago to 1,238, according to The Cyber Express.
Newly emergent vulnerabilities accounted for the majority of flaws added to the KEV catalog this year, but 60-70 of the fresh entries were years-old bugs. The oldest of which is the Internet Explorer use-after-free issue, tracked as CVE-2012-4792, from 2012.
Meanwhile, OS command injection vulnerabilities enabling unauthorised control were the most prevalent flaw type, followed by deserialisation of untrusted data, use-after-free, path traversal, and improper authentication bugs.
