CVE-2015-7072
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 · unediteddyld in Apple iOS before 9.2, tvOS before 9.1, and watchOS before 2.1 mishandles segment validation, which allows attackers to execute arbitrary code in a privileged context via a crafted app.
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 confidenceThe dyld dynamic linker in Apple iOS before 9.2, tvOS before 9.1, and watchOS before 2.1 has a flaw in segment validation that allows crafted applications to execute arbitrary code in a privileged context, potentially giving attackers elevated system privileges.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the Apple device OS typeOn the device, go to Settings > General > About and note which OS is listed (iOS, tvOS, or watchOS)Affected if The device runs iOS, tvOS, or watchOS - this CVE affects all three
-
Determine iOS version on iPhone or iPadOn the device, go to Settings > General > About > Version to see the installed iOS version number (for example, 9.1, 9.0, 8.4)Affected if The iOS version is 9.1 or lower (9.1, 9.0, 8.x, etc.)
-
Determine watchOS version on Apple WatchOpen the Watch app on the paired iPhone, go to General > About > Version to see the installed watchOS version numberAffected if The watchOS version is 2.0 or lower (2.0, 1.x, etc.)
-
Determine tvOS version on Apple TVOn Apple TV, go to Settings > General > About > Version to see the installed tvOS version numberAffected if The tvOS version is 9.0 or lower (9.0, 8.x, etc.)
If the device runs iOS 9.1 or earlier, watchOS 2.0 or earlier, or tvOS 9.0 or earlier, the environment is affected by this vulnerability in the dyld dynamic linker.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the vendor-supplied OS updates: upgrade to iOS 9.2 or later, tvOS 9.1 or later, or watchOS 2.1 or later. In enterprise environments, use MDM to verify and enforce patching across all managed devices.
iOS 9.2+, watchOS 2.1+, tvOS 9.1+
- For iOS devices: Go to Settings > General > Software Update, then download and install iOS 9.2 or later
- For Apple Watch: Open the Watch app on iPhone, go to General > Software Update, and install watchOS 2.1 or later
- For Apple TV: Go to Settings > System > Software Updates, then update to tvOS 9.1 or later
- Ensure device is connected to power and Wi-Fi before initiating updates
- After updating, verify the update was successful by checking the software version in Settings > General > About
