iOS 18.3.2 primarily focuses on addressing a critical security vulnerability and includes some bug fixes. However, there are a few known issues and changes associated with this update:
1. Security Fix: The most significant aspect of iOS 18.3.2 is its security patch, which fixes a vulnerability in WebKit, the engine powering Safari and other browsers on iOS. This vulnerability could allow maliciously crafted web content to escape the Web Content sandbox, potentially leading to unauthorized access to device data. The issue was previously mitigated in iOS 17.2, but this update provides additional security reinforcements[1][2][5].
2. Streaming Playback Issue: iOS 18.3.2 also resolves an issue that could prevent the playback of certain streaming content. This fix ensures smoother video playback for users[3][5].
3. Apple Intelligence Re-enabled: Some users have reported that the update re-enables Apple Intelligence by default for those who had previously disabled it. Users can manually disable this feature if desired[2].
4. General Stability and Performance: While not explicitly listed in Apple's release notes, some users have noted improvements in system stability and responsiveness following the update. However, specific issues like Wi-Fi disconnections or app loading delays were not universally addressed in this update[4][10].
5. Compatibility: iOS 18.3.2 is compatible with iPhone XS and newer models, as well as various iPad models, including iPad Pro, iPad Air (3rd generation and later), iPad (7th generation and later), and iPad mini (5th generation and later)[1].
Overall, while iOS 18.3.2 is primarily a security-focused update, it also includes some general bug fixes and improvements to enhance user experience. However, some users may still encounter specific issues not addressed by this update.
