Critical WebKit Security Patch in iOS 18.3.2 and macOS 15.3.2: What You Need to Know

Security Fix in iOS 18.3.2 and Other Updates

Apple has released new bug fix and security updates for its major platforms, including iOS 18.3.2, macOS 15.3.2, and visionOS 2.3.2. The primary focus of these updates is a single security fix addressing a WebKit vulnerability.

Impact:

• Maliciously crafted web content may be able to break out of the Web Content sandbox.
• This issue was originally addressed in iOS 17.2, but Apple has now implemented a supplementary fix due to an extremely sophisticated attack targeting specific individuals on versions before iOS 17.2.

Description:

• An out-of-bounds write issue was addressed with improved checks to prevent unauthorized actions.
• The vulnerability has been around for over a year, but the additional fix is necessary to ensure complete security.

Apple is not aware of any exploits that occurred after the initial fix in iOS 17.2. However, users are encouraged to update their devices to the latest version to stay protected.
