NVD · uneditedA memory corruption issue was addressed with improved state management. This issue is fixed in Safari 15.6, macOS Monterey 12.5. 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 confidenceMemory corruption vulnerability in WebKit (Safari's browser engine) allows arbitrary code execution when processing maliciously crafted web content. The issue was addressed through improved state management in Safari 15.6 and macOS Monterey 12.5.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed Safari versionOpen Safari, go to Safari > About Safari to view the version number, or run 'defaults read /Applications/Safari.app/Contents/Info CFBundleShortVersionString' in TerminalAffected if Version is earlier than 15.6
-
Check macOS versionOpen System Preferences > About This Mac, or run 'sw_vers -productVersion' in TerminalAffected if Version is 12.0.0 through 12.4.x (12.5 and later are fixed)
-
Identify WebKit-based browsers in useCheck Applications folder for browsers that use WebKit engine (Safari, older iOS-based browsers, or WebKit wrappers). Run 'defaults read /Applications/Safari.app/Contents/Info CFBundleName' to confirm SafariAffected if Safari is the primary browser and version check shows vulnerability
User is affected if Safari version is below 15.6 on macOS 12.0.0 through 12.4.x, as these combinations contain the vulnerable WebKit memory corruption issue.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped12.515.6
Apply Apple security update (Safari 15.6+, macOS 12.5+) to fix the memory corruption vulnerability. Until patched, restrict web browsing to trusted sites to reduce exposure.
Safari 15.6 or later; macOS Monterey 12.5 or later
- Check current Safari version: Open Safari > Safari menu > About Safari
- Check current macOS version: Apple menu > About This Mac
- For Safari: Update to Safari 15.6 via Software Update (Apple menu > System Preferences > Software Update)
- For macOS Monterey: Update to version 12.5 via Apple menu > System Preferences > Software Update
- After updating, verify the fix by checking Safari version shows 15.6 or later and macOS shows 12.5 or later
