Apple Releases Critical Security Updates for macOS Sonoma, macOS Sequoia, and iOS 18
On February 11, 2026, Apple rolled out a series of essential security updates targeting older operating systems, including macOS Sonoma 14.8.4, macOS Sequoia 15.7.4, and iOS 18.7.5. These updates coincide with the release of newer versions such as macOS Tahoe 26.3 and iOS 26.3, underscoring Apple’s commitment to maintaining the security of its entire user base, regardless of the device’s age.
Key Highlights of the Updates:
– macOS Sonoma 14.8.4: This update addresses multiple vulnerabilities that could potentially allow malicious applications to execute arbitrary code with kernel privileges. By improving memory management and input validation, Apple has fortified the system against such exploits.
– macOS Sequoia 15.7.4: Similar to the Sonoma update, this release patches critical security flaws, including issues within the WebKit framework that could lead to arbitrary code execution when processing malicious web content. Enhanced bounds checking and memory handling have been implemented to mitigate these risks.
– iOS 18.7.5: This update focuses on rectifying vulnerabilities that could allow attackers to bypass sandbox restrictions, potentially leading to unauthorized access to user data. Apple has addressed these concerns by refining access controls and bolstering the overall security architecture.
The Importance of Updating:
Cybersecurity threats are continually evolving, with attackers constantly seeking new methods to exploit system vulnerabilities. By releasing these updates, Apple aims to preemptively close security gaps that could be exploited by malicious entities.
