iOS 18.3.2 contains a supplementary fix for an actively exploited vulnerability.



On Tuesday, following the launch of the third developer beta of iOS 18.4, Apple released iOS 18.3.2. While the update itself is relatively minor, it includes an important security fix related to web browsing.



Specifically, iOS 18.3.2 contains a supplementary fix for a WebKit vulnerability that was believed to have been fully patched with iOS 17.2. According to Apple's website, the vulnerability meant that attackers were able to use maliciously crafted web content to break out of the iOS Web Content sandbox.

The security issue was reportedly used as part of an extremely sophisticated attack targeting high-profile individuals, particularly those with devices running versions older than iOS 17.2.

The iOS 18.3.2 update fully resolves this WebKit vulnerability, as Apple fixed an out-of-bounds write issue through the addition of improved security checks that prevent unauthorized actions. The security issue was also patched on Mac via macOS Sequoia 15.3.2 and Safari 18.3.1 for macOS Ventura. The Apple Vision Pro received the same fix with the visionOS 2.3.2 update.

It's important to always keep your operating system up-to-date. Apple's latest security fixes ensure that bad actors have a much more difficult time obtaining your private user data, on some occasions even patching actively used exploits, as was the case with the iOS 18.3.2 update.

    But if you have disabled Apple Intelligence it will turn it back on and you will have to disable it again.

    After installing the update on my 2020 SE, my phone became incredibly slow. Turns out System Data had grown by more than 10% and eaten up much of my phone's minimal free space. Multiple reboots made little difference. I ended up doing a local backup, after which the free space was restored.

    Interestingly, it did not turn it back on for me, on either iOS or MacOS -- both still off.

    Did the update reenable Apple Intelligence for you? Mine (on iPadOS) is still off (in Settings) after the update to 18.3.2. I turned it off a few weeks ago and so far it’s remained off.

    I don’t have an iPhone compatible with Apple Intelligence, so I can’t check iOS though.

    It did for me on my iPad and Mac. There’s a thread over on MacRumours that’s showing it’s a bit hit and miss. I probably should have said ‘may turn it back on’.
