Apple has released security updates for more than two dozen security vulnerabilities across iPhone, iPad, and macOS Tahoe,including yet another image parsing vulnerability that could compromise your device.

This update delivers security fixes that were first made available in the iOS 27 and iPadOS 27 betas.

Updates for your particular device

The table below shows which updates are available and points you to the relevant security content for each one.

How to update your Apple devices

How to update your iPhone or iPad

For iOS and iPadOS users, here’s how to check if you’re using the latest software version:

Go to Settings > General > Software Update. You will see if there are updates available and be guided through installing them.

Turn on Automatic Updates if you haven’t already—you’ll find it on the same screen.

How to update macOS on any version

To update macOS on any supported Mac, use the Software Update feature, which Apple designed to work consistently across all recent versions. Here are the steps:

• Click the Apple menu in the upper-left corner of your screen.
• Choose System Settings (or System Preferences on older versions).
• Select General in the sidebar, then click Software Update on the right. On older macOS, just look for Software Update directly.
• Your Mac will check for updates automatically. If updates are available, click Update Now (or Upgrade Now for major new versions) and follow the on-screen instructions. Before you upgrade to macOS Tahoe 26, please read these instructions.
• Enter your administrator password if prompted, then let your Mac finish the update (it might need to restart during this process).
• Make sure your Mac stays plugged in and connected to the internet until the update is done.

Technical details

Of the 27 vulnerabilities, CVE-2026-65346 is the one that stands out. It is an ImageIO integer-overflow bug in which merely processing a malicious image may result in arbitrary code execution, a substantially stronger stated impact than the many “crash-only” findings in this release.

ImageIO is Apple’s framework that handles image parsing. An integer overflow means the vulnerability lets a malicious hacker trick the program into performing an integer operation where the result exceeds the allocated memory space. This can lead to attackers running malicious programs or gaining elevated privileges. In this case, it allows the attacker to run code on the target’s device.

There is no indication in Apple’s advisory that CVE-2026-65346 or any other listed vulnerability was exploited in the wild, but cybercriminals will often try to reverse engineer the patch to come up with an exploit, or the researchers who found it will post a proof-of-concept once everyone has had a chance to apply the update. At that point, these vulnerabilities can be used against you.

Microsoft Defender’s latest patch bypass shows a familiar problem.

A newly disclosed Microsoft Defender flaw called ShieldBreak shows that fixing one attack path doesn’t always close every route to the same result.

Microsoft has assigned ShieldBreak the identifier CVE-2026-69414 and confirmed it is an elevation of privilege (EoP) vulnerability in the Microsoft Malware Protection Engine. Microsoft says it is still working on a security update.

If that sounds somehow familiar, you’re probably thinking of RoguePlanet, another vulnerability in Defender that Microsoft acknowledged on June 16 and patched on July 8.

A short timeline

At the time, the published exploit for RoguePlanet was described as depending on a race condition, meaning it was not guaranteed to work the same way on every machine. That was one reason the vulnerability was concerning but still somewhat limited from a practical point of view.

Microsoft’s July fix should have closed the door on that problem. But security fixes do not always eliminate a weakness at the root of the problem. Sometimes they block one known attack path, while a researcher later finds a different route to reach the same end result.

That appears to be what happened here. ShieldBreak has been described as a patch bypass because it reportedly sidesteps the earlier RoguePlanet fix, although it uses a different exploitation method rather than simply repeating the original attack.

In August, the same researcher disclosed ShieldBreak, and Microsoft responded by publishing a new advisory for CVE-2026-69414.

The advisory says the issue has been publicly disclosed, proof-of-concept (PoC) exploit code exists, exploitation is considered more likely, and no official fix is available yet. Microsoft says it is working on one.

How to stay safe

Until Microsoft releases a fix, the most important protection is preventing untrusted code from running on your computer in the first place. ShieldBreak is a local privilege escalation issue, so an attacker first needs some level of access to the machine.

Based on the best public reporting available right now, ShieldBreak appears to require Microsoft Defender to be enabled in order to work. Public testing indicates that the exploit does not succeed when Defender is off or when another product is registered as the active antivirus provider.

So, narrowly speaking, disabling Defender appears to stop this specific ShieldBreak chain from working. However, that is not a good safety recommendation for most people. Turning off your antivirus removes an important layer of protection and could leave your computer exposed to other attacks.

For home users, all that means:

• Install Microsoft’s security updates as soon as they become available.
• Be very careful with downloads, email attachments, cracked software, and “fix” tools from random websites.
• Keep backups of important files somewhere not directly connected to the PC.
• Use an up-to-date, real-time anti-malware solution to alert you about and remove threats from your computer.
