Apple Releases Security Updates for iOS, macOS, and More — Over 100 Vulnerabilities Fixed

Apple has released a significant wave of security updates across its platforms, addressing more than 100 vulnerabilities affecting iOS, macOS, and related operating systems. The updates—rolled out on Monday—include fixes for critical flaws that could enable attackers to exfiltrate data, execute arbitrary code, or bypass key security protections.

These patches are part of Apple’s ongoing commitment to strengthening the resilience of its ecosystem, as cyber threats become increasingly automated and AI-assisted.

Key Updates for iOS and iPadOS

The release of iOS 26.1 and iPadOS 26.1 introduces fixes for 56 vulnerabilities, with 19 issues specifically targeting the WebKit browser engine used by Safari and all third-party browsers on iOS.

Apple’s advisory notes that several WebKit vulnerabilities could:

• Allow websites to exfiltrate cross-origin data.

• Cause unexpected process crashes and memory corruption.

• Enable applications to monitor user keystrokes.

A notable contribution to these discoveries came from Google’s Big Sleep AI agent, which has been instrumental in identifying zero-day-level vulnerabilities before they can be weaponized. According to Google, Big Sleep proactively detects flaws that threat actors may be preparing to exploit, effectively preempting attacks.

Beyond WebKit, the new update resolves flaws across over two dozen system components, closing potential pathways for sandbox escape, data leaks, and privilege escalation.

macOS Updates: Tahoe, Sequoia, and Sonoma

Apple’s macOS Tahoe 26.1 update patches 105 vulnerabilities, including 45 shared with iOS and iPadOS. Among these, 18 involve WebKit, underscoring the cross-platform importance of Apple’s browser engine security.

The patched vulnerabilities could have enabled:

• Kernel memory corruption and privilege escalation.

• System crashes or denial-of-service conditions.

• File tampering, sandbox escapes, and data leaks.

Additionally, Apple issued updates for macOS Sequoia 15.7.2 and macOS Sonoma 14.8.2, each containing dozens of fixes.

Other Apple platforms—including tvOS, watchOS, visionOS, and Xcode—also received coordinated patches to ensure consistent security coverage across devices.

Broader Impact and Security Implications

This latest patch cycle highlights Apple’s increasingly proactive approach to security collaboration with external researchers and AI-driven systems. The discovery of many of these bugs before real-world exploitation suggests an evolution toward predictive vulnerability management, where threats are identified and mitigated ahead of active attacks.

Users are strongly encouraged to update their devices immediately, as delayed patching remains a leading cause of compromise in both consumer and enterprise environments.
