The most recent Mac OS X flaw added to the known-exploited list is CVE-2014-0497, on 17 September 2024. We keep watching the known-exploited list.
Is Mac OS X listed under other names? Yes.
Apple also lists Mac OS X under more specific names, such as Mac OS X Server and Mac OS X Preview.app. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.
Which versions of Mac OS X do the exploited flaws hit?
Each exploited flaw lists the versions it affects, usually as ranges. "before 10.14.4" means every version up to, but not including, 10.14.4. Find your version, then patch.
