CVE-2022-32831: An out-of-bounds read was addressed with improved bounds checking.

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, macOS Monterey 12.5. Processing a maliciously crafted AppleScript binary may result in unexpected termination or disclosure of process memory.

Security readout for executives and security teams

Plain-English summary

CVE-2022-32831 is a macOS flaw where opening or processing a malicious AppleScript binary could crash the affected process or expose process memory. It is not described as remotely exploitable without user interaction, but the potential memory disclosure and availability impact make patching important.

Executive priority

Treat this as a high-priority workstation patching issue, especially for managed Mac fleets handling scripts or files from outside the organization. There is no provided evidence of active exploitation, so urgency is driven by impact and patch availability rather than confirmed attacks.

Technical view

Apple describes an out-of-bounds read in macOS, addressed with improved bounds checking. The CVSS vector is local, low complexity, no privileges required, user interaction required, with high confidentiality and availability impact. The issue maps to CWE-125 and is fixed in Catalina Security Update 2022-005, Big Sur 11.6.8, and Monterey 12.5.

Likely exposure

Exposure is most likely on macOS systems below Catalina Security Update 2022-005, Big Sur 11.6.8, or Monterey 12.5 that can process AppleScript binaries. The source bundle does not provide exact vulnerable build ranges beyond the fixed releases.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires a user or workflow to process a maliciously crafted AppleScript binary, which may cause process termination or process memory disclosure.

Researcher notes

Key constraints are local attack vector and required user interaction. The CVE does not name the specific component beyond AppleScript binary processing, and affected version data is broad. Validation should focus on OS build status and workflows that process AppleScript content.

Mitigation direction

  • Apply Apple's fixed macOS updates listed for Catalina, Big Sur, or Monterey.
  • Prioritize systems that process AppleScript files from users or external sources.
  • Avoid opening untrusted AppleScript binaries until patched.
  • For unsupported macOS versions, check current Apple guidance and upgrade paths.

Validation and detection

  • Inventory macOS versions and compare them with Apple's fixed releases.
  • Confirm Catalina systems have Security Update 2022-005 where applicable.
  • Confirm Big Sur systems are at 11.6.8 or later.
  • Confirm Monterey systems are at 12.5 or later.
  • Review endpoint telemetry for crashes linked to AppleScript processing.

Out-of-bounds Read

Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
