Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a sandbox escape vulnerability in iOS and iPadOS where improved memory handling was needed. An app could potentially break out of its sandbox due to a memory corruption issue, allowing it to execute code beyond its intended security boundaries.

MitigationUpdate affected iOS devices to iOS 16.2 or later, and iPadOS 16.2 or later, as this version contains the fix for the memory handling vulnerability that allowed sandbox escape.

Work through these to decide whether this CVE applies to you.

  1. Check iOS version
    Go to Settings > General > About on the iPhone and locate the version number (such as 16.1, 15.7, or earlier)
    Affected if The installed version is lower than 16.2 (for example, 16.1, 15.7.5, 15.6)

A device is affected if it runs iOS version 16.1 or earlier, or iPadOS version 16.1 or earlier.
