Official description

NVD · unedited

A memory corruption issue was addressed with improved validation. This issue is fixed in iOS 16.7.8 and iPadOS 16.7.8, iOS 17.4 and iPadOS 17.4, macOS Monterey 12.7.6, macOS Sonoma 14.4, macOS Ventura 13.6.7, tvOS 17.4, visionOS 1.1, watchOS 10.4. An attacker with arbitrary kernel read and write capability may be able to bypass kernel memory protections. Apple is aware of a report that this issue may have been exploited.

Technical summary

dbcve analysis · high confidence

Memory corruption vulnerability in Apple kernel allows attackers with existing arbitrary kernel read/write capabilities to bypass kernel memory protections. The issue was addressed through improved memory validation. This is a defense-in-depth bypass that requires the attacker to already have kernel-level access.

MitigationApply vendor-supplied security updates to all affected Apple devices: iOS 16.7.8/17.4, iPadOS 16.7.8/17.4, macOS 12.7.6/13.6.7/14.4, tvOS 17.4, visionOS 1.1, and watchOS 10.4.

dbcve checks

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

Check iOS version on iPhone

Go to Settings > General > About on the device and note the 'Version' field (e.g., 17.3). Alternatively, run 'sw_vers' via SSH or MDM.

Affected if Version is less than 16.7.8, OR version is 17.0 through 17.3.x (anything >= 17.0 but < 17.4)
Check iPadOS version on iPad

Go to Settings > General > About on the device and note the 'Version' field. Alternatively, run 'sw_vers' via SSH or MDM.

Affected if Version is less than 16.7.8, OR version is 17.0 through 17.3.x (anything >= 17.0 but < 17.4)
Check macOS version

Run 'sw_vers -productVersion' in Terminal, or go to System Settings > About > macOS version.

Affected if Version is 12.0 through 12.7.5, OR 13.0 through 13.6.6, OR 14.0 through 14.3.x (anything >= 14.0 but < 14.4)
Check tvOS version

Run 'sw_vers -productVersion' via SSH if available, or check via Apple TV Settings > General > About.

Affected if Version is less than 17.4 (any version before 17.4)
Check visionOS version

Check via Vision Pro Settings > General > About.

Affected if Version is less than 1.1 (any version before 1.1)
Check watchOS version

Open the Watch app on paired iPhone, go to My Watch > General > About, or check on Apple Watch via Settings > General > About.

Affected if Version is less than 10.4 (any version before 10.4)

A device is affected if its operating system version falls within any of the vulnerable ranges listed for that product: the device must be running an unpatched version of iOS, iPadOS, macOS, tvOS, visionOS, or watchOS.

Interim mitigation

Apply vendor-supplied security updates to all affected Apple devices: iOS 16.7.8/17.4, iPadOS 16.7.8/17.4, macOS 12.7.6/13.6.7/14.4, tvOS 17.4, visionOS 1.1, and watchOS 10.4.

Recommended fix High confidence

Upgrade to iOS/iPadOS 16.7.8 or 17.4, macOS 12.7.6/13.6.7/14.4, tvOS 17.4, visionOS 1.1, or watchOS 10.4 as applicable to your device

Back up your device data before updating
Determine your current device and OS version via Settings > General > About (iOS/iPadOS), System Settings or About This Mac (macOS), or Settings > General > About (tvOS, watchOS, visionOS)
For iPhone/iPad: Update to iOS/iPadOS 16.7.8 or iOS/iPadOS 17.4 via Settings > General > Software Update
For Mac: Update to macOS Monterey 12.7.6, macOS Ventura 13.6.7, or macOS Sonoma 14.4 via System Settings > General > Software Update
For Apple TV: Update to tvOS 17.4 via Settings > General > Apple TV Software Updates
For Apple Watch: Update to watchOS 10.4 via the Watch app on iPhone > General > Software Update
For Apple Vision Pro: Update to visionOS 1.1 via Settings > General > Software Update
After update, verify the new version is installed

Caveat Standard iOS/macOS update risks apply - ensure backup before upgrading; some older devices may not support newer OS versions

This CVE is on CISA’s actively-exploited list, so the clock is real — a vetted specialist can deliver a reviewed fix for your staging environment quickly.

You’ll deal with our team directly and deploy the reviewed fix to staging first — never straight to production.

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.

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.
