Description A use-after-free issue exists in the WebKit rendering engine, which occurs when the software continues to reference memory that has already been freed. This flaw stems from improper memory management within the HTML parsing logic.

There are reports that this issue has been exploited in sophisticated attacks targeting specific individuals on versions of iOS prior to 26.
