Apple has launched iOS 18.5, an important update aimed at tackling a range of security vulnerabilities and improving system performance. This update includes 33 key reasons why users should upgrade their devices without delay. The iOS 18.5 update not only provides critical security fixes but also addresses various bugs and offers new features for enhanced privacy and user experience.
Among the most significant updates in iOS 18.5 are patches for two major flaws in the Kernel. These flaws could allow a remote attacker to cause unexpected crashes or system terminations, posing a serious threat to device security. In addition to these Kernel vulnerabilities, iOS 18.5 also addresses multiple security bugs within WebKit, Apple’s browser engine. Notably, CVE-2025-24213, a type confusion issue identified by the Google V8 Security Team, could potentially lead to memory corruption.
The update also fixes issues in Core Bluetooth, which could allow apps to access sensitive information without permission. Additionally, a flaw in iCloud document sharing could enable unauthorized users to activate sharing settings without authentication, leaving files exposed. Another fix in iOS 18.5 involves a vulnerability in mDNSResponder, tracked as CVE-2025-31222, which could be exploited to escalate user privileges on affected devices.
Another critical issue resolved in iOS 18.5 is CVE-2024-8176, a code execution vulnerability in the libexpat library, which affects many open-source projects, including Apple’s software. Addressing this flaw is important for preventing the execution of malicious code on iPhones and other Apple devices.
