On the time of publication, Apple was not conscious of those vulnerabilities being exploited within the wild, which is nice information. Nonetheless, know that they’ve been extra broadly marketed, it is solely a matter of time earlier than somebody tries to make use of them, so it is essential to replace as quickly as doable.

macOS 14.4.1 (and macOS 13.6.6 for that matter) additionally embody these two patches, which is probably going why Apple waited till it launched these Mac updates earlier than disclosing the particular vulnerabilities.
Nonetheless, along with supplying essential safety patches, macOS 14.4.1 consists of bug fixes for issues you will have skilled utilizing macOS 14.4. In line with Apple’s launch notes, this replace fixes a problem the place macOS would not acknowledge USB hubs when related to exterior shows, and one bug the place copy protected Audio Unit plug-ins wouldn’t open or move validation. Maybe most significantly, the replace fixes a problem the place apps that use Java could give up unexpectedly.
