Apple on Monday rolled out security updates to patch tens of vulnerabilities across its operating systems, and it has finally released macOS Big Sur and Catalina patches for two exploited vulnerabilities.
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.
Described as an out-of-bounds write issue impacting AppleAVD, CVE-2022-22675 can allow an application to execute code with kernel privileges. CVE-2022-22674 affects the Intel graphics driver and it has been described as an out-of-bounds read issue that can lead to the disclosure of kernel memory. Both flaws were reported by anonymous researchers.
No information has been made public on the attacks exploiting CVE-2022-22675 and CVE-2022-22674.
Tens of other vulnerabilities were resolved with the latest Big Sur and Catalina updates on Monday, most of them leading to arbitrary code execution. Elevation of privilege, memory leak, Gatekeeper check bypass, DoS and other types of issues were also squashed.
On Monday, Apple also released software updates for macOS Monterey, iOS, and iPadOS, addressing tens of vulnerabilities in each operating system. The company is apparently not aware of any attacks exploiting these weaknesses.
The latest updates for watchOS and tvOS have started rolling out with fixes for over 20 security defects each. These operating systems are based on iOS and they share many of the same vulnerabilities.
Security updates were also released for Xcode and Safari.
