CVE-2025-46298

Vulnerability

Overview CVE-2025-46298 is a memory handling issue in WebKit that affects multiple Apple platforms, including Safari, iOS, iPadOS, macOS Tahoe, tvOS, visionOS, and watchOS. The vulnerability is triggered when processing maliciously crafted web content, leading to an unexpected process crash [1][2][3][4]. Apple addressed the issue with improved memory handling in the 26.2 releases of these operating systems.

Exploitation

An attacker could exploit this vulnerability by hosting or injecting specially crafted web content that a victim would view in Safari or another affected WebKit-based browser. No additional authentication or user interaction beyond viewing the content is required, as the crash occurs during content processing [1].

Impact

Successful exploitation could result in a denial-of-service condition where the browser or application processing the web content crashes. While the crash itself does not directly enable code execution or data theft, it may disrupt user activity and could potentially be used as part of a larger attack chain [1][2][3][4].

Mitigation

Apple released security updates on December 12, 2025, for macOS Tahoe 26.2, iOS 26.2 and iPadOS 26.2, tvOS 26.2, visionOS 26.2, and watchOS 26.2. Users should update their devices to the latest available versions to protect against this vulnerability [1][2][3][4].
