Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An authorization issue was addressed with improved state management. This issue is fixed in iOS 15.8.4 and iPadOS 15.8.4, iOS 16.7.11 and iPadOS 16.7.11, iOS 18.3.1 and iPadOS 18.3.1, iPadOS 17.7.5. A physical attack may disable USB Restricted Mode on a locked device. Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals.

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 · high confidence

This is an authorization bypass vulnerability in iOS/iPadOS where a physical attack can disable USB Restricted Mode on a locked device. The issue stems from improper state management in the authorization logic. USB Restricted Mode is designed to block data access via the Lightning port after a device has been locked for a specified period, but this vulnerability allows an attacker with physical access to bypass this protection.

MitigationApply the available iOS/iPadOS security updates (iOS 15.8.4, 16.7.11, 18.3.1; iPadOS 15.8.4, 16.7.17.7.5, 18.3.1) to affected devices. For high-risk individuals targeted by sophisticated attacks, ensure devices are always in secure physical custody and consider additional physical security controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

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

  1. Check iOS version on iPhone
    Go to Settings > General > About > Version and note the build number
    Affected if Version is less than 15.8.4, or between 16.0 and 16.7.10, or between 17.0 and 17.7.5, or between 18.0 and 18.3.0 (all vulnerable)
  2. Check iPadOS version on iPad
    Go to Settings > General > About > Version and note the build number
    Affected if Version is less than 15.8.4, or between 16.0 and 16.7.10, or between 17.0 and 17.7.5, or between 18.0 and 18.3.0 (all vulnerable)
  3. Confirm device lock behavior with USB accessory
    Lock the device, wait over 1 hour, then attempt to connect a USB accessory. If the accessory connects, USB Restricted Mode may have been bypassed
    Affected if USB accessory successfully connects after device has been locked for more than 1 hour (indicating the bypass may have been exploited)

The device is affected if it runs any iOS version lower than 15.8.4, 16.0-16.7.10, 17.0-17.7.5, or 18.0-18.3.0, as these versions contain the USB Restricted Mode bypass flaw.

Interim mitigation

Apply the available iOS/iPadOS security updates (iOS 15.8.4, 16.7.11, 18.3.1; iPadOS 15.8.4, 16.7.17.7.5, 18.3.1) to affected devices. For high-risk individuals targeted by sophisticated attacks, ensure devices are always in secure physical custody and consider additional physical security controls.

Recommended fix High confidence

iOS 15.8.4 / iPadOS 15.8.4, iOS 16.7.11 / iPadOS 16.7.11, iOS 17.7.5 / iPadOS 17.7.5, or iOS 18.3.1 / iPadOS 18.3.1 depending on your current major version

  1. 1. Back up your device data before performing the update
  2. 2. Connect your iPhone or iPad to power and Wi-Fi
  3. 3. Go to Settings > General > Software Update
  4. 4. Download and install the appropriate update for your current iOS version: For iOS 15.x devices, install iOS 15.8.4; For iOS 16.x devices, install iOS 16.7.11; For iOS 17.x devices, install iOS 17.7.5; For iOS 18.x devices, install iOS 18.3.1
  5. 5. After updating, verify the fix by ensuring USB Restricted Mode remains enabled under Settings > Face ID & Passcode (or Touch ID & Passcode) > USB Accessories toggle is disabled when the device is locked
Caveat Standard iOS point release upgrade risks apply (ensure backup before updating); note that iOS 15.8.4 is the final security update for iOS 15 devices
