Apple has released iOS 18.4.1 and iPadOS 18.4.1, which offers no new features but fixes two critical vulnerabilities. For both fixes, Apple says on its security updates page that it is “aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on iOS.”

The release notes are small for this one. Outside of the security fixes, this release only claims to fix a bug with wireless CarPlay.

This update provides important bug fixes, security updates, and addresses a rare issue that prevents wireless CarPlay connection in certain vehicles.

Even though you may not be a specific individual target of hackers, you should update your iPhones and iPads now. The security bulletins are as follows:
