The exploited vulnerabilities, tracked as CVE-2022-22675 and CVE-2022-22674, were disclosed in late March. However, at the time, they were only patched in iOS, iPadOS and macOS Monterey, leaving Big Sur and Catalina users exposed.
Apple has now patched CVE-2022-22675 with the release of macOS Big Sur 11.6.6, watchOS 8.6, and tvOS 15.5, and CVE-2022-22674 with Security Update 2022-004 for Catalina. While the Big Sur advisory mentions exploitation of the security hole, the Catalina advisory does not.
