But Apple noted in a terse advisory that it’s “aware of a report that this issue may have been actively exploited.”
The updates, iOS 16.5.1 (a), iPadOS 16.5.1 (a), macOS Ventura 13.4.1 (a), and Safari 16.5.2, are available for devices running the following operating system versions:
iOS 16.5.1 and iPadOS 16.5.1
macOS Ventura 13.4.1
macOS Big Sur and macOS Monterey
Apple has addressed 10 zero-day vulnerabilities in its software since the start of 2023. It also arrives weeks after the company rolled out patches to fix three zero-days, two of which have been weaponized by unidentified actors in connection with an espionage campaign called Operation Triangulation.
Update:
Apple has pulled the software update after reports emerged that installing the patches caused certain websites like Facebook, Instagram, and Zoom to throw an “Unsupported Browser” error on Safari.
