Release overview

iOS 17.1.2 was publicly released on November 30, 2023. iOS 17.1.2 was a security-only public update centered on two WebKit vulnerabilities.[1][2]

Apple documented an out-of-bounds read that could expose sensitive information and a memory-corruption issue that could enable code execution. Both entries noted reports of exploitation against versions before iOS 16.7.1.[1][2]
