Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.
Exploited Before the Fix
Apple flags a fix as possibly exploited when it has a credible report that the flaw was used against real people before the patch. This one is the reason to update today.

WebKit Exploited
Maliciously crafted web content may be able to break out of Web Content sandbox. This is a supplementary fix for an attack that was blocked in iOS 17.2. (Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.)
An out-of-bounds write issue was addressed with improved checks to prevent unauthorized actions.
CVE-2025-24201
