Back up your iPhone, connect it to power and Wi-Fi, then open Settings > General > Software Update. Install the update offered for your device and check that screen afterward to confirm the installed version. Apple’s September 28, 2026 bulletin says iOS 26.7.1 fixes a flaw for iPhone 11 and later, but the version shown on your own iPhone—not a universal version number—is the right guide to what you can install.
What Apple warned about
Apple’s September 28, 2026 security bulletin for iOS 26.7.1 and iPadOS 26.7.1 identifies CVE-2026-86950 in CoreGraphics. Apple says processing a maliciously crafted file may lead to arbitrary code execution. The bulletin says the issue was addressed with improved bounds checking and lists iPhone 11 and later as compatible with the update.
Apple’s exploitation wording is limited: it is “aware of a report” that the issue “may have been exploited in an extremely sophisticated attack against specific targeted individuals” on iOS versions before iOS 27. That is not evidence that all iPhone users were attacked.
Because compatible models and software states differ, do not assume one version number applies to every iPhone. Apple says the phone’s Software Update screen shows its installed version and whether an update is available. Check the offer and details shown for your device using Apple’s iPhone update guide.

Back up and prepare before installing
Apple says installing the latest iOS leaves your data and settings unchanged, but advises backing up first. A backup is prudent preparation, not a sign that an update is expected to erase your information.
Make an iCloud backup
- Connect the iPhone to Wi-Fi.
- Open Settings > [your name] > iCloud > iCloud Backup.
- Tap Back Up Now and remain connected to Wi-Fi until it finishes. The screen shows the date and time of the latest completed backup. Apple’s iCloud backup instructions describe this process.
You can also back up using a computer. Choose iCloud or a computer based on what you already have set up and can complete; Apple’s cited guidance does not establish one as universally better.

Connect to power and Wi-Fi
Before a wireless update, connect the iPhone to power and a Wi-Fi network. Make sure the connection is usable and allow time for the download and installation.
Install the update from iPhone Settings
- Open Settings > General > Software Update.
- Review the installed version and any update offered. Confirm the version and details on the screen apply to your iPhone.
- Tap Download and Install, then follow the on-screen instructions.
- When installation finishes, return to Settings > General > Software Update and check the installed version shown there.
Apple also supports automatic installation overnight when the iPhone is charging and connected to Wi-Fi, and says it notifies users before installation. For a security update you want to install promptly, check Settings and start the process yourself rather than waiting for an automatic update.

If the update is missing or will not install
Apple lists several possible reasons a wireless update may not appear or complete: the iPhone may not support the software, storage may be insufficient, the download may take longer than expected, the update server may be unreachable, or installation may fail. The phone needs compatible software, an internet connection and enough available storage; keeping it on power also helps. See Apple’s troubleshooting steps for an iPhone that will not update.
- Check compatibility and storage: confirm your model supports the offered software and free enough space if Settings reports a storage issue.
- Retry network problems: if you see a server or verification error, retry on the same network. If the problem continues, try another network.
- Use a computer if needed: Apple documents computer updates as an alternative when wireless updating is unavailable or unsuccessful. The route depends on the computer and software you have; check your available equipment and connectors before buying anything.
Apple’s guidance about web-based attacks says that if an iPhone cannot be updated, users may enable Lockdown Mode if it is available, while still aiming to update to the latest iOS as soon as possible. That is general web-attack guidance, not a mitigation Apple specifically identified for CVE-2026-86950. Apple discusses this advice in its guidance on updating iOS to protect against web attacks.

If Apple sent you a threat notification
A public security bulletin is not the same as an Apple threat notification directed to an individual. If you received a personal notification, verify it by signing in directly at account.apple.com; Apple says a genuine notification appears at the top of your account page.
Apple says threat notifications will not ask you to click links, open files, install apps or profiles, or provide your Apple Account password or verification code by email or phone. Apple strongly suggests notified users seek expert help, including the 24/7 Digital Security Helpline run by the nonprofit Access Now. A public bulletin alone does not mean you received a personal notification.
