iOS 17.7.1 Update for iPhone Changelog

According to Apple, the iOS 17.7.1 update is only available for iPhone models that have not been updated to iOS 18 or the latest iOS 18.1 software. It fixes a vulnerability called CVE-2024-44239, which Apple says could put an application at risk of leaking sensitive kernel state. This is reported to be a disclosure issue that has since been resolved with improved personal data editing for log entries.

Additionally, CVE-2024-44269 creates a risk of allowing a malicious program to use shortcuts to access restricted files due to a logic issue. An information disclosure issue was also reported in Siri that could allow a sandbox application to access sensitive user data in system logs.
