What is CVE-2025-24201?

CVE-2025-24201 is an out-of-bounds write vulnerability affecting various Apple products, including iOS, iPadOS, visionOS, macOS, and Safari. This vulnerability arises from inadequate checks that allow malicious web content to potentially bypass the Web Content sandbox, posing a risk to the integrity and security of affected systems. If exploited, it can lead to unauthorized actions on these devices, compromising user data and system stability, thereby negatively impacting organizations that rely on these platforms for operations.

Technical Details

The vulnerability has been characterized as an out-of-bounds write issue, which typically occurs when a program writes data outside the intended boundary of a buffer, leading to unpredictable behavior. Apple addressed this issue in multiple software updates, specifically versions 2.3.2 for visionOS, 18.3.2 for iOS and iPadOS, 15.3.2 for macOS Sequoia, and 18.3.1 for Safari. The improvements aimed to enhance checks that prevent the exploitation of this vulnerability, specifically addressing an attack that had been reportedly blocked in an earlier version of iOS (17.2).

Potential impact of CVE-2025-24201

  1. Unauthorized Access: Exploitation of this vulnerability could allow attackers to gain unauthorized access to sensitive data, leading to information leaks and breaches of confidentiality.

  2. System Compromise: Malicious exploitation could result in the alteration or corruption of system processes, potentially crippling devices or allowing for further malware deployment within organizational networks.

  3. Targeted Attacks: While no active exploitation has been confirmed in the wild, reports suggest that this vulnerability may have been utilized in sophisticated targeted attacks against select individuals, indicating that it could be leveraged for high-value espionage or data theft scenarios.

CISA Reported
