iOS 18.3.2 focuses primarily on critical security fixes rather than new features. Released on March 12, 2025, this update addresses important WebKit vulnerabilities, particularly the CVE-2025-24201 out-of-bounds write issue. You'll need to download a 400-600MB file and might need to re-enter Wi-Fi passwords after installation. Compatible with iPhone XS and newer models, this update serves as a stopgap before iOS 18.4's arrival in April. The security improvements work silently behind the scenes to protect your device.
Apple has released iOS 18.3.2, a critical security update that addresses several important vulnerabilities and bug fixes. This update arrived on March 12, 2025, serving as a stopgap measure before the more feature-rich iOS 18.4 expected in early April. Based on current information, this update appears to be purely speculative as no official announcement has been made.
The primary focus of iOS 18.3.2 is security enhancement, particularly fixing an out-of-bounds write issue in WebKit identified as CVE-2025-24201. This vulnerability previously allowed potential attackers to bypass important security measures in your device's web browser components.

iOS 18.3.2 is compatible with iPhone XS and newer models, with a download size of approximately 400-600 megabytes. You can access this update through your Settings app under Software Updates.
While this release addresses critical bugs, it doesn't introduce new features or interface changes. Those improvements are being reserved for iOS 18.4, which is currently in beta testing for developers.
The upcoming iOS 18.4 will deliver more substantial enhancements, including Priority Notifications and an Apple News+ Food section. Apple employees are currently conducting internal testing of iOS 18.3.2 before its official release. If you're looking for new functionality rather than security patches, you might want to wait for that more expansive update.
After installing iOS 18.3.2, you may need to re-enter Wi-Fi passwords, but this minor inconvenience helps establish more secure connections. The update also aims to resolve persistent Wi-Fi connectivity problems and app freezing issues reported by users.
Apple has simultaneously released security updates for other products including iPads and Apple Vision Pro, indicating the importance of these security patches across their ecosystem.
While iOS 18.3.2 mightn't fulfill expectations for exciting new features, it delivers on its primary purpose: strengthening your device's security foundation and fixing critical bugs that impact daily use.
