Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

iOS 18.1.1 was a security-only maintenance release in Apple’s consumer notes. Its bulletin documented fixes in JavaScriptCore and WebKit for malicious web content that could lead to code execution or cross-site scripting.[1][2]

Apple’s exploitation notice for both vulnerabilities specifically referred to Intel-based Mac systems. This archive therefore does not characterize the notice as evidence that the flaws were actively exploited on iPhone.[3]
