CVE-2025-31233

Vulnerability

Details

CVE-2025-31233 is a memory corruption vulnerability in Apple's media processing framework. The root cause is insufficient input sanitization when handling crafted video files. This flaw can be triggered by processing a maliciously crafted video file, leading to unexpected app termination or corruption of process memory [2][4].

Exploitation

An attacker can exploit this vulnerability by delivering a specially crafted video file to a target user. No special privileges are required beyond the user opening the file in any application that processes video content. The attack surface is broad, affecting multiple Apple platforms including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS [1][2][3][4].

Impact

Successful exploitation results in either a denial of service (app termination) or memory corruption, which could potentially be leveraged for further compromise. The CVSS v3 score of 6.3 (Medium) reflects the need for user interaction and the potential for limited impact on confidentiality, integrity, and availability.

Mitigation

Apple has addressed this issue in the following updates released on May 12, 2025: iOS 18.5, iPadOS 18.5, iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, macOS Ventura 13.7.6, tvOS 18.5, visionOS 2.5, and watchOS 11.5 [1][2][3][4].
