Executive Summary

This is a memory corruption vulnerability caused by insufficient locking mechanisms. It allows malicious web content to trigger an unexpected crash in Safari by exploiting improper memory handling.

Detection Guidance

This vulnerability is specific to Apple software and relates to memory corruption in Safari and web content processing. Detection primarily involves checking installed software versions rather than running commands. Verify if your device is running affected versions of iOS, iPadOS, macOS Tahoe, or Safari.

Impact Analysis

If exploited, this vulnerability could cause Safari to crash when processing specially crafted web content. This may lead to denial of service or potential exposure to further attacks during the crash state.

Compliance Impact

Mitigation Strategies

Update your Apple devices to the latest versions: iOS 18.7.10 or later, iPadOS 18.7.10 or later, macOS Tahoe 26.6.2 or later. For Safari, ensure you are using the patched versions included in these updates. Avoid processing untrusted web content until updates are applied.
