CVE-2022-26750
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 buffer overflow issue was addressed with improved memory handling. This issue is fixed in macOS Monterey 12.4. An application may be able to execute arbitrary code with kernel privileges.
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 · moderate confidenceA buffer overflow vulnerability in macOS Monterey's kernel component allows a local application to execute arbitrary code with kernel-level privileges due to improper memory handling. This represents a local privilege escalation vulnerability where an attacker could gain full system control.

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 macOS versionOpen Terminal and run: sw_vers -productVersionAffected if The version returned is 12.0, 12.1, 12.2, or 12.3 (any 12.0.x up to but not including 12.4)
-
Confirm macOS Monterey release nameRun: sw_vers -productVersion and verify the major version is 12Affected if Major version is 12 and minor version is less than 4
-
Verify kernel version as secondary checkRun: uname -r to see kernel release, which on Monterey follows pattern 21.x.xAffected if Kernel version indicates Monterey (21.x.x) and OS version is below 12.4
If the system is running any macOS Monterey version from 12.0 through 12.3.x, it is affected by this kernel buffer overflow vulnerability.
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 · scoped12.4
Upgrade to macOS Monterey 12.4 or later to apply the memory handling fix that addresses this buffer overflow vulnerability.
macOS Monterey 12.4 or later (recommended: latest stable macOS release such as 12.6, 13.x, or 14.x)
- Back up your Mac using Time Machine or another backup solution before updating
- Open System Preferences (or System Settings on macOS Ventura and later)
- Click on Software Update
- Allow macOS to check for updates
- If macOS Monterey 12.4 or later is available, click Update Now to download and install the update
- Alternatively, download macOS Monterey 12.4 or later directly from the Mac App Store
- Restart your Mac when prompted to complete the installation
- After updating, verify the installation by going to Apple menu > About This Mac and confirming the macOS version is 12.4 or later
