CVE-2025-24196
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA type confusion issue was addressed with improved memory handling. This issue is fixed in macOS Sequoia 15.4, macOS Sonoma 14.7.5. An attacker with user privileges may be able to read kernel memory.
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 confidenceA type confusion vulnerability in macOS kernel allows a local attacker with standard user privileges to read kernel memory due to improper memory handling during certain operations.

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.
-
Determine the installed macOS versionRun 'sw_vers -productVersion' in Terminal to obtain the exact macOS version numberAffected if The version displayed is 14.0 through 14.7.4, or 15.0 through 15.3.x (any version below 14.7.5 or 15.4)
-
Identify the macOS release nameRun 'sw_vers -productVersion' and note whether the major version corresponds to Sonoma (14.x) or Sequoia (15.x)Affected if Running Sonoma 14.x below 14.7.5 or Sequoia 15.x below 15.4
-
Verify kernel version as secondary confirmationRun 'uname -r' to check the kernel release version, though this may not directly map to the security update versionAffected if Kernel version corresponds to an unpatched macOS release within the affected ranges
The system is affected if it runs macOS Sonoma 14.0-14.7.4 or macOS Sequoia 15.0-15.3, as these versions contain the vulnerable kernel memory handling code that allows unauthorized kernel memory reads.
Generated from the published advisory. Verify against your own configuration.
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 · scoped14.7.515.4
Apply the vendor security updates: macOS Sequoia 15.4 or macOS Sonoma 14.7.5 to patch the kernel memory handling vulnerability.
macOS Sonoma 14.7.5 or macOS Sequoia 15.4
- Back up your Mac using Time Machine or another backup solution before upgrading
- Upgrade to macOS Sonoma 14.7.5 if running macOS 14.x (Sonoma), or upgrade to macOS Sequoia 15.4 if running macOS 15.x
- Verify the upgrade was successful by checking System Settings > General > About to confirm the installed version
