On the heels of macOS Monterey 12.2.1, which patched a critical WebKit flaw, Apple has released updates for macOS Big Sur (11.6.4) and macOS Catalina (2022-002) that also bring important security fixes. Apple has not released any details about the updates and there are no published CVE (Common Vulnerabilities and Exposures) entries.
Big Sur 11.6.4 and the Security Update 2022-02 for Catalina come shortly after Big Sur 11.6.3 and the Security Update 2022-01 for Catalina were released on January 26, the same day Apple released macOS 12.2. The WebKit flaw was fixed for Big Sur and Catalina in Safari 15.3, so these updates likely address a separate issue. Apple’s only notes about the update are that they “improve the security of macOS.”
