CVE-2025-43350 is a permissions-related vulnerability affecting Apple iOS and iPadOS operating systems prior to version 26.1. The vulnerability arises from improper enforcement of access controls on content displayed or accessible from the device lock screen. An attacker exploiting this flaw can view restricted content without authentication or user interaction, potentially exposing sensitive information visible on the lock screen. The issue is classified under CWE-276, indicating an incorrect permission assignment or enforcement. The vulnerability has a CVSS v3.1 base score of 2.4, reflecting low severity due to limited confidentiality impact and no effect on integrity or availability. Exploitation requires physical access or proximity to the device but does not require the device to be unlocked or user interaction, making it a privacy concern rather than a system compromise. Apple addressed this issue by implementing additional restrictions on lock screen content access in iOS and iPadOS 26.1. No known exploits have been reported in the wild, and the vulnerability was publicly disclosed in November 2025. The affected versions are all prior to 26.1, with no specific version range detailed. This vulnerability highlights the importance of strict permission checks on lock screen features to prevent unauthorized data exposure.

The primary impact of CVE-2025-43350 is the unauthorized disclosure of restricted content from the lock screen, which can lead to privacy violations for users. While the vulnerability does not compromise device integrity or availability, the exposure of sensitive information such as notifications, messages, or other lock screen content can be exploited for social engineering or targeted attacks. Organizations relying on Apple mobile devices for sensitive communications or data access may face increased risk of information leakage if devices are lost, stolen, or accessed by unauthorized individuals. The low CVSS score reflects the limited scope and difficulty of exploitation, but the impact on confidentiality can be significant in environments where lock screen content contains critical or private information. Since no authentication or user interaction is required, the vulnerability can be exploited quickly if physical access is gained. However, the lack of known exploits in the wild suggests limited active threat currently. Overall, the impact is primarily on user privacy and confidentiality rather than system security or operational continuity.

To mitigate CVE-2025-43350, organizations and users should immediately update all affected Apple devices to iOS and iPadOS version 26.1 or later, where the vulnerability is patched. Beyond patching, administrators should review and configure lock screen settings to minimize exposure of sensitive content, such as disabling lock screen notifications for sensitive apps or restricting access to certain features from the lock screen. Employing strong device access controls, including biometric authentication and complex passcodes, can reduce the risk of unauthorized physical access. Organizations should also implement mobile device management (MDM) policies that enforce timely OS updates and restrict lock screen content visibility. Educating users about the risks of leaving sensitive information visible on the lock screen and encouraging prompt reporting of lost or stolen devices will further reduce exposure. Regular audits of device security posture and lock screen configurations can help identify and remediate residual risks. Since no known exploits exist, proactive patching and configuration hardening remain the most effective defenses.
