Security readout for executives and security teams
Plain-English summary
CVE-2022-26758 is a macOS Monterey vulnerability where a malicious local application could alter memory shared between processes. Apple fixed it in macOS Monterey 12.4. The business risk is highest on Macs that allow untrusted apps or remain below the fixed version.
Executive priority
Prioritize remediation for managed Mac fleets, especially developer, executive, and BYOD-adjacent systems. This is not described as remotely exploitable, but it can affect confidentiality and integrity if a malicious app runs locally.
Technical view
The issue is a memory corruption flaw, mapped to CWE-362, involving state management around interprocess shared memory. CVSS 3.1 is 7.1 with local attack, low complexity, low privileges, no user interaction, and high confidentiality and integrity impact. Availability impact is not indicated.
Likely exposure
Exposure is limited to affected macOS Monterey systems that have not been updated to macOS Monterey 12.4 or later. Exploitation requires a malicious local application with low privileges.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The attack scenario is local application abuse, not remote unauthenticated exploitation.
Researcher notes
Evidence is limited to Apple and CVE metadata. The CVE describes unexpected changes in shared interprocess memory and a fix via improved state management. No exploit details, indicators, or additional affected Apple platforms are provided in the supplied sources.
Mitigation direction
- Update affected macOS Monterey systems to version 12.4 or later.
- Review Apple advisory guidance for any environment-specific instructions.
- Restrict installation and execution of untrusted local applications.
Validation and detection
- Inventory macOS Monterey devices and record OS versions.
- Confirm each affected system is running macOS Monterey 12.4 or later.
- Check endpoint controls for untrusted application execution risk.
- Monitor Apple advisories for any revised guidance.

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
