Vulnerability
CVE-2025-31278 is a memory corruption vulnerability in WebKit, the browser engine used by Safari and other Apple applications. The issue stems from improper memory handling when processing maliciously crafted web content, which could allow an attacker to exploit the memory corruption.

The attack vector is remote over the network, making it accessible to attackers without physical access.
Impact
Successful exploitation could lead to memory corruption, which might enable arbitrary code execution or cause a denial of service. While the official description only states memory corruption, such issues often allow an attacker to run arbitrary code in the context of the affected application.
Mitigation
Apple addressed the issue with improved memory handling in Safari 18.6, iOS 18.6 and iPadOS 18.6, iPadOS 17.7.9, macOS Sequoia 15.6, tvOS 18.6, visionOS 2.6, and watchOS 11.6 [1][2][3][4]. Users should update their devices to the latest available versions to protect against potential attacks.
