CVE-2025-24163 is a vulnerability identified in Apple iOS and iPadOS operating systems that can cause an application to terminate unexpectedly when parsing a specially crafted file. This issue arises from insufficient validation or checks during file parsing, which leads to an unhandled error condition causing the app to crash. The vulnerability affects multiple Apple platforms including iOS, iPadOS, macOS Sequoia, tvOS, visionOS, and watchOS, with fixes released in versions such as iOS 18.3, iPadOS 17.7.4, and macOS Sequoia 15.3 and later. The CVSS 3.1 base score is 5.5, indicating a medium severity level. The attack vector is local (AV:L), requiring the attacker to have local access and for the user to interact with the malicious file (UI:R). No privileges are required (PR:N), and the scope is unchanged (S:U). The impact is limited to availability (A:H) with no confidentiality or integrity loss. This vulnerability can be exploited by tricking a user into opening or processing a maliciously crafted file, causing the targeted app to crash and potentially disrupting user operations. No known exploits have been reported in the wild, but the issue could be leveraged for denial of service attacks against applications handling untrusted files. Apple addressed the vulnerability by implementing improved validation and checks during file parsing to prevent unexpected terminations.

The primary impact of CVE-2025-24163 is denial of service through unexpected application termination. For organizations, this can lead to disruption of critical workflows if apps handling important files crash unexpectedly. While the vulnerability does not compromise data confidentiality or integrity, repeated crashes can degrade user productivity and trust in affected applications. In environments where Apple devices are widely used, such as enterprises relying on iOS/iPadOS apps for business operations, this could cause operational interruptions. Additionally, malicious actors could exploit this flaw to target specific users or departments by sending crafted files, causing targeted denial of service. Although no remote exploitation without user interaction is possible, social engineering could facilitate triggering the vulnerability. The absence of known exploits in the wild reduces immediate risk but does not eliminate future exploitation potential. Overall, the impact is moderate but significant in contexts where application availability is critical.

To mitigate CVE-2025-24163, organizations and users should promptly update all affected Apple devices to the patched OS versions: iOS 18.3 or later, iPadOS 17.7.4 or later, macOS Sequoia 15.3 or later, and corresponding versions for tvOS, visionOS, and watchOS. Enforce strict update policies and verify device compliance regularly. Educate users to avoid opening files from untrusted or unknown sources, especially those received via email, messaging apps, or downloads. Implement application whitelisting and sandboxing where possible to limit the impact of app crashes. Monitor application logs and device behavior for signs of unexpected terminations that could indicate attempted exploitation. For enterprise environments, consider deploying mobile device management (MDM) solutions to enforce security configurations and updates. Finally, maintain backups and recovery procedures to minimize disruption from potential denial of service incidents.
