Lock Screen Notification Content Disclosure in iOS and iPadOS

IdentifiersCVE-2025-43309CWE-200

CVE-2025-43309 is a logic flaw in iOS and iPadOS that could allow notification contents to be viewed from the Lock Screen. Apple states the issue was addressed with improved checks and fixed in iOS 26 and iPadOS 26. The vulnerability affects the device lock-screen notification handling path, where insufficient validation or state checking can expose notification content that should remain protected while the device is locked. Apple credits Abhay Kailasia (@abhay_kailasia) from C-DAC Thiruvananthapuram India with reporting the issue.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker with physical access to a vulnerable iOS device may be able to disclose the contents of notifications directly from the Lock Screen. This can expose sensitive information such as message previews, one-time codes, email subjects, or other private notification data without unlocking the device, resulting in a confidentiality and privacy breach.

Mitigation

If you can’t patch tonight, do this now.

Until the update can be applied, reduce exposure by disabling notification previews on the Lock Screen, limiting which apps may show notifications while locked, requiring Face ID/Touch ID or passcode before showing sensitive previews, and maintaining physical control of devices.

Remediation

Patch, then assume compromise.

Upgrade affected devices to iOS 26 or iPadOS 26, where Apple fixed the issue through improved checks in the relevant lock-screen notification handling logic.
