Private Relay DNS Query Leak in Apple Platforms
CVE-2025-43419 is an Apple vulnerability affecting Safari 26, tvOS 26, watchOS 26, iOS 26, iPadOS 26, and visionOS 26 prior to the fix. According to the provided Apple advisory, the issue could allow a remote attacker to view leaked DNS queries while Private Relay is enabled. Apple states the issue was addressed with improved state management. Although other provided content associates the same CVE in WebKitGTK/WPE WebKit with memory corruption from maliciously crafted web content, the Apple advisory gives specific product-impact details for Apple platforms indicating a privacy leak involving DNS query handling under Private Relay rather than a memory-safety condition. Based on the supplied material, the vulnerable condition is best characterized as a state-management flaw that can expose DNS query information despite the expectation of Private Relay protection.
