watchOS 11.4 Security Update

What watchOS 11.4 Fixes

watchOS 11.4, released April 1, 2025, fixes 51 vulnerabilities in 32 parts of the system, according to Apple's security advisory.

Apple says one of these flaws — CVE-2025-24201 — may already have been exploited. That makes watchOS 11.4 an update to install now rather than at the weekend.

It has since been superseded: the newest security release for watchOS 11 is watchOS 11.6, from July 29, 2025, which includes these fixes.

Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.

Exploited Before the Fix

Apple flags a fix as possibly exploited when it has a credible report that the flaw was used against real people before the patch. This one is the reason to update today.

• WebKit Exploited

  Maliciously crafted web content may be able to break out of Web Content sandbox. This is a supplementary fix for an attack that was blocked in iOS 17.2. (Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.)

  An out-of-bounds write issue was addressed with improved checks to prevent unauthorized actions.

  CVE-2025-24201

Which Devices Get watchOS 11.4

Apple lists watchOS 11.4 for: Apple Watch Series 6 and later.

How to Install watchOS 11.4

Open the Watch app on the paired iPhone, then General → Software Update. The watch needs to be on its charger and within range of the iPhone.

Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past watchOS 11.4 there is nothing to do.
