CVE-2025-43282 is a vulnerability stemming from a double free memory management issue in Apple’s iOS and iPadOS platforms, as well as other Apple operating systems such as macOS, tvOS, visionOS, and watchOS. A double free occurs when a program attempts to free the same memory location twice, which can corrupt the memory management data structures, potentially leading to unpredictable behavior including crashes. In this case, a malicious application running on the device can exploit this flaw to cause unexpected system termination, effectively resulting in a denial of service (DoS) condition. The vulnerability requires local access with limited privileges (AV:L) and user interaction (UI:R), meaning an attacker must convince a user to run a malicious app or code. The vulnerability does not allow for unauthorized disclosure or modification of data (no confidentiality or integrity impact), but it severely impacts availability by crashing the system. Apple has fixed this issue by improving memory management in the affected components, releasing patches in iOS 18.6, iPadOS 18.6 and 17.7.9, macOS Sequoia 15.6, Sonoma 14.7.7, Ventura 13.7.7, tvOS 18.6, visionOS 2.6, and watchOS 11.6. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the limited attack vector and impact scope. No known exploits have been observed in the wild, but the vulnerability remains a risk until devices are updated. The underlying weakness is classified as CWE-415: Double Free.

The primary impact of CVE-2025-43282 is denial of service through unexpected system termination on affected Apple devices. For organizations, this can disrupt business operations by causing device instability or crashes, particularly in environments relying heavily on iOS, iPadOS, or macOS devices for critical workflows. Although the vulnerability does not compromise data confidentiality or integrity, repeated crashes could lead to productivity loss, user frustration, and potential cascading failures in systems dependent on these devices. In sectors such as healthcare, finance, or government, where device availability is crucial, this vulnerability could be exploited to degrade service or interrupt operations. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, especially in environments where users may install untrusted applications or open malicious links. The broad range of affected Apple operating systems increases the scope of potential impact across consumer, enterprise, and specialized device users.

To mitigate CVE-2025-43282, organizations should prioritize deploying the official patches released by Apple for all affected operating systems, including iOS 18.6, iPadOS 18.6 and 17.7.9, macOS Sequoia 15.6, Sonoma 14.7.7, Ventura 13.7.7, tvOS 18.6, visionOS 2.6, and watchOS 11.6. Beyond patching, organizations should enforce strict application installation policies to prevent users from installing untrusted or unsigned apps, reducing the risk of local exploitation. Implement mobile device management (MDM) solutions to centrally manage updates and restrict app sources. Educate users about the risks of installing unknown apps and the importance of applying system updates promptly. Monitor device stability and logs for signs of unexpected crashes that could indicate exploitation attempts. For high-security environments, consider restricting user permissions to limit the ability to install or run potentially malicious applications. Regularly review and audit installed applications to detect unauthorized or suspicious software. Finally, maintain backups and incident response plans to quickly recover from potential denial of service events.
