Apple on Monday announced patches for a record number of vulnerabilities across its desktop and mobile operating systems, including more than 200 flaws patched with the latest major releases: iOS 27 and macOS Golden Gate 27.
iOS 27 and iPadOS 27 include fixes for about 126 security flaws, 20 of which affect the kernel.
macOS Golden Gate 27 addresses 210 vulnerabilities, roughly 100 of which are shared with the iOS 27 release.
macOS Tahoe 26.7 patches 153 unique CVEs, including 26 security defects in the kernel that could lead to memory corruption, privilege escalation, system termination, and information leaks.
While the vast majority of the issues were discovered in 2026, the macOS update also fixes CVE-2022-3437, a medium-severity heap-based buffer overflow in Samba (within Heimdal) that could lead to denial-of-service (DoS) attacks.
Approximately 100 of the resolved security defects affect both operating systems. The fixes target more than 90 platform components, including AppleKeyStore, Authentication Services, Foundation, Safe Browsing, Sandbox, Security, TCC, and WebKit.
On Monday, Apple also rolled out iOS 26.7 and iPadOS 26.7 with patches for over 80 vulnerabilities (including approximately 70 resolved in iOS 27 and iPadOS 27), and macOS Sequoia 15.8 with over 150 patches (more than 140 also found in macOS Tahoe 26.7).
Additionally, the company released tvOS 27, watchOS 27, and visionOS 27 with patches for dozens of security flaws each, Safari 27 with six fixes, and Xcode 27 with one patch.
Apple makes no mention of any of these security defects being exploited in the wild. Users are advised to update their devices as soon as possible.
