Kernel passcode attempt delay logic issue in Apple operating systems

IdentifiersCVE-2025-30432CWE-840

CVE-2025-30432 is a kernel logic flaw in Apple platforms caused by improper state management. Apple states that a malicious app may be able to attempt passcode entries on a locked device and thereby cause escalating time delays after four failures. The issue affects multiple Apple operating systems, including visionOS, iOS, iPadOS, tvOS, and macOS, and was fixed with improved state management in visionOS 2.4, macOS Ventura 13.7.5, tvOS 18.4, iPadOS 17.7.6, iOS 18.4, iPadOS 18.4, and macOS Sonoma 14.7.5. Based on the available information, this is a state/logic handling weakness in the kernel’s passcode attempt and lock-state enforcement path rather than a memory-safety bug.

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.

Successful exploitation allows a malicious local app to interfere with passcode attempt handling on a locked device. The documented effect is the ability to attempt passcode entries and trigger the escalating delay mechanism after four failures. This impacts the integrity of the device lock/passcode enforcement workflow and could facilitate unauthorized passcode-guessing attempts or manipulation of lockout behavior. The available content does not state that this issue by itself yields code execution or privilege escalation.

Mitigation

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

If immediate patching is not possible, reduce exposure by limiting installation and execution of untrusted or unnecessary applications, especially on devices that may be left locked but accessible to locally installed apps. Enforce strong application control and physical security over affected devices until updates can be applied. No vendor-provided workaround is described in the supplied content.

Remediation

Patch, then assume compromise.

Apply the vendor fixes released by Apple. Apple indicates the issue is fixed in visionOS 2.4, macOS Ventura 13.7.5, tvOS 18.4, iPadOS 17.7.6, iOS 18.4, iPadOS 18.4, and macOS Sonoma 14.7.5. Upgrading affected devices to the relevant patched OS version is the primary remediation.
