CVE-2025-43292 is a vulnerability identified in Apple macOS operating systems, specifically addressed in the recent releases macOS Sequoia 15.7 and macOS Tahoe 26. The vulnerability arises from a race condition related to improper state handling within the system. A race condition occurs when the timing or order of events can be manipulated to cause unexpected behavior, often leading to security flaws. In this case, the flaw could allow a malicious application to access sensitive user data that it should not normally be able to reach. Although the exact technical mechanism is not detailed, the vulnerability likely involves concurrent processes or threads accessing shared resources without proper synchronization, enabling unauthorized data exposure. The vulnerability affects unspecified versions of macOS prior to the patched releases, and no known exploits have been reported in the wild at the time of publication. The absence of a CVSS score indicates that the vulnerability is newly disclosed and has not yet been fully assessed for severity by standard scoring frameworks. However, the nature of the vulnerability—unauthorized access to sensitive user data—indicates a significant security concern. The fix involves improved state handling to prevent the race condition, highlighting that the root cause was a timing or state management flaw in the operating system's codebase.

For European organizations, this vulnerability poses a risk primarily to those using Apple macOS devices, including desktops and laptops. Sensitive user data exposure can lead to breaches of personal information, intellectual property, or confidential business data, potentially violating GDPR and other data protection regulations. The impact extends to sectors where macOS is prevalent, such as creative industries, software development, education, and certain government agencies. Unauthorized data access could facilitate further attacks, including privilege escalation or lateral movement within networks. Although no active exploitation is currently known, the potential for exploitation exists until systems are patched. This could result in reputational damage, regulatory fines, and operational disruptions. Organizations relying on macOS for critical workflows should consider this vulnerability a priority for remediation to maintain compliance and security posture.

European organizations should take the following specific actions beyond generic patching advice: 1) Immediately inventory all macOS devices to identify those running versions prior to Sequoia 15.7 or Tahoe 26. 2) Prioritize deployment of the official Apple updates that address this vulnerability, ensuring that update mechanisms are secure and verified. 3) Implement application whitelisting and strict endpoint controls to limit the installation and execution of untrusted or unauthorized applications that could exploit the race condition. 4) Monitor system logs and behavior for unusual access patterns or attempts to access sensitive data, leveraging endpoint detection and response (EDR) tools tailored for macOS. 5) Educate users about the risks of running untrusted applications and encourage prompt installation of security updates. 6) For organizations with sensitive data, consider additional data encryption at rest and in transit to mitigate the impact of unauthorized access. 7) Coordinate with IT and security teams to integrate this vulnerability into incident response plans and vulnerability management workflows.
