Apple CVE-2025-43529

Immediately update all Apple devices to patched versions released by Apple in their coordinated security update. Install Safari 26.2 on macOS systems via Software Update or direct download from support.apple.com/en-us/125884. Update iOS and iPadOS devices to version 18.7.3 (advisory support.apple.com/en-us/125885) or version 26.2 (advisory support.apple.com/en-us/125886) depending on device compatibility. Update macOS Tahoe to version 26.2 per support.apple.com/en-us/125889. Update tvOS to 26.2 (support.apple.com/en-us/125890), visionOS to 26.2 (support.apple.com/en-us/125891), and watchOS to 26.2 (support.apple.com/en-us/125892). No effective workarounds exist for WebKit vulnerabilities given the engine's deep integration across the operating system; disabling JavaScript would break legitimate functionality while not fully mitigating use-after-free conditions that may trigger during HTML/CSS processing. Prioritize iOS/iPadOS updates for high-value individuals given confirmed exploitation on mobile platforms. Organizations should verify update deployment through mobile device management systems and treat this as an emergency patch cycle given active exploitation.
