A vulnerability in WebKit affecting Apple iOS, iPadOS, and macOS could be triggered when Safari processes maliciously crafted web content. Apple indicated the issue was addressed through improved memory handling, which suggests a memory-safety flaw in WebKit’s handling of attacker-controlled web content. Successful triggering causes Safari to crash unexpectedly. Fixed versions include iOS 18.7.10, iPadOS 18.7.10, iOS 26.6.1, iPadOS 26.6.1, and macOS Tahoe 26.6.2.
