CVE-2022-32853: An out-of-bounds read issue was addressed with improved input validation.

An out-of-bounds read issue was addressed with improved input validation. 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-2022-32853 is a macOS flaw triggered by processing a maliciously crafted AppleScript binary. A successful attack could crash the affected process or expose process memory. It requires user interaction and is fixed in Apple’s listed Catalina, Big Sur, and Monterey security updates.

Executive priority

Treat this as a high-priority macOS patching item, not a confirmed emergency. User interaction lowers immediate exploitability, but possible memory disclosure and process termination justify timely remediation across managed Mac fleets.

Technical view

Apple describes an out-of-bounds read, CWE-125, addressed with improved input validation. CVSS 3.1 is 7.1: local attack vector, low complexity, no privileges required, user interaction required, high confidentiality and availability impact, and no integrity impact.

Likely exposure

Exposure is most likely on Macs running macOS versions earlier than Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, or macOS Monterey 12.5, especially where users can open or process AppleScript binaries from untrusted sources.

Exploitation context

The provided bundle does not cite active exploitation, and the CVE is not marked as CISA KEV. The attack requires a malicious AppleScript binary to be processed, so phishing, file delivery, or local user workflow abuse are plausible contexts, but not confirmed by the sources.

Researcher notes

Evidence is limited to Apple and CVE records. The affected surface is described as AppleScript binary processing, but the bundle does not name a deeper component, exploit availability, indicators of compromise, or standalone mitigations beyond Apple’s fixed releases.

Mitigation direction

  • Update Catalina systems with Security Update 2022-005 or later vendor guidance.
  • Update Big Sur systems to macOS 11.6.8 or later vendor guidance.
  • Update Monterey systems to macOS 12.5 or later vendor guidance.
  • Limit handling of untrusted AppleScript binaries until affected Macs are updated.
  • Check Apple advisories for currently supported upgrade paths.

Validation and detection

  • Inventory macOS endpoints and identify Catalina, Big Sur, and Monterey systems.
  • Confirm installed versions meet or exceed Apple’s fixed releases.
  • Review endpoint management reports for missing Apple security updates.
  • Check whether users or workflows process AppleScript binaries from external sources.
  • Document exceptions and track them against Apple’s current guidance.

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.
