CVE-2025-46285 is an integer overflow vulnerability identified in Apple’s iOS and iPadOS operating systems, as well as other Apple platforms including macOS Sequoia, Sonoma, Tahoe, tvOS, visionOS, and watchOS. The root cause is related to the handling of 64-bit timestamps, where an integer overflow could allow an application with limited privileges to escalate its privileges to root level. This vulnerability falls under CWE-190 (Integer Overflow or Wraparound). The issue was addressed by Apple through adopting 64-bit timestamps and releasing security updates in iOS 18.7.3, iPadOS 18.7.3, and corresponding versions of other Apple OSes. The vulnerability requires an attacker to have local access with low privileges (PR:L) but does not require user interaction (UI:N), making it easier to exploit once local access is obtained. The CVSS v3.1 score of 7.8 indicates high severity due to the potential for complete system compromise (confidentiality, integrity, and availability all rated high). Although no known exploits have been reported in the wild, the vulnerability poses a significant risk if weaponized, especially in environments where untrusted apps can be installed or where physical device access is possible. The flaw enables privilege escalation, which could be leveraged to bypass security controls, install persistent malware, or exfiltrate sensitive data.

The impact of CVE-2025-46285 is substantial for organizations relying on Apple devices, particularly iPhones, iPads, and Macs running affected OS versions. Successful exploitation allows an app with limited privileges to gain root access, effectively bypassing all user and system-level security restrictions. This can lead to full device compromise, including unauthorized access to sensitive corporate data, installation of persistent malware, and disruption of device availability. For enterprises, this elevates the risk of insider threats, targeted attacks, and lateral movement within networks. The vulnerability also threatens user privacy and data integrity, potentially exposing confidential communications and credentials. Given the widespread use of Apple devices in business, education, and government sectors, the vulnerability could facilitate espionage, sabotage, or ransomware attacks. Although exploitation requires local access, the prevalence of app sideloading, device theft, or insider threat scenarios increases the risk. The absence of known exploits in the wild currently limits immediate impact but does not diminish the urgency to patch.

Organizations should immediately deploy the security updates released by Apple for iOS 18.7.3, iPadOS 18.7.3, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, and watchOS 26.2. Beyond patching, organizations should enforce strict app installation policies to prevent unauthorized or untrusted apps from running, including disabling sideloading where possible. Device management solutions should be used to monitor and restrict privilege escalations and detect anomalous app behavior indicative of exploitation attempts. Physical device security must be enhanced to prevent unauthorized local access, including strong authentication and encryption. Security teams should audit device logs for suspicious activity and educate users about the risks of installing untrusted applications. Additionally, organizations should consider implementing runtime protection and endpoint detection solutions tailored for Apple platforms to detect exploitation attempts. Regular vulnerability assessments and penetration testing focusing on privilege escalation vectors can help identify residual risks.
