A use after free issue was addressed with improved memory management. This issue is fixed in macOS Monterey 12.3, Safari 15.4, watchOS 8.5, iOS 15.4 and iPadOS 15.4, tvOS 15.4. Processing maliciously crafted web content may lead to arbitrary code execution.

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 confidence

A use-after-free vulnerability in WebKit allows arbitrary code execution when processing maliciously crafted web content. This affects Safari 15.4 and multiple Apple operating systems (iOS, iPadOS, macOS, watchOS, tvOS) prior to their 15.4/12.3 updates.

MitigationApply the vendor-supplied security updates: Safari 15.4, macOS Monterey 12.3, iOS/iPadOS 15.4, watchOS 8.5, or tvOS 15.4 and later.

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 checks

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

  1. Check Safari version
    Open Safari, go to Safari > About Safari (or press Cmd+Comma) to view the installed version number
    Affected if The version displayed is earlier than 15.4 (for example, 15.3.x or earlier)
  2. Check macOS version
    Click Apple menu > About This Mac to view the macOS version
    Affected if The macOS version shown is 12.0, 12.1, or 12.2 (versions 12.0 through 12.2 are within the affected range)
  3. Check iOS or iPadOS version
    Go to Settings > General > About on the device to view the iOS/iPadOS version
    Affected if The version displayed is earlier than 15.4 (for example, 15.3.x or earlier)
  4. Check watchOS version
    Open the Watch app on iPhone, go to My Watch > General > About to view the watchOS version
    Affected if The version displayed is earlier than 8.5 (for example, 8.4.x or earlier)
  5. Check tvOS version
    Go to Settings > General > About on Apple TV to view the tvOS version
    Affected if The version displayed is earlier than 15.4 (for example, 15.3.x or earlier)

If any Apple product (Safari, macOS, iOS, iPadOS, watchOS, or tvOS) on your system is found to be at a version lower than the minimum fixed version (15.4 for Safari/iOS/iPadOS/tvOS/watchOS, or 12.3 for macOS), the WebKit use-after-free vulnerability is present and could be triggered by visiting malicious web content.
