CVE-2022-32820: An out-of-bounds write issue was addressed with improved input validation.

An out-of-bounds write issue was addressed with improved input validation. This issue is fixed in iOS 15.6 and iPadOS 15.6, macOS Big Sur 11.6.8, watchOS 8.7, tvOS 15.6, macOS Monterey 12.5, Security Update 2022-005 Catalina. An app may be able to execute arbitrary code with kernel privileges.

Security readout for executives and security teams

Plain-English summary

CVE-2022-32820 is an Apple kernel-level memory corruption issue. A malicious app could potentially run code with kernel privileges after user interaction, giving it deep control over a device. Apple addressed it with improved input validation in listed iOS, iPadOS, macOS, watchOS, and tvOS updates.

Executive priority

Treat this as a high-priority patching item for Apple fleets, especially employee endpoints and mobile devices. The bundle does not support emergency active-exploitation language, but kernel-level code execution risk warrants prompt remediation and exception tracking.

Technical view

The issue is CWE-787 out-of-bounds write with CVSS 7.8. The vector is local, low complexity, no privileges required, and user interaction required. Impact is high for confidentiality, integrity, and availability because successful exploitation may allow arbitrary code execution with kernel privileges.

Likely exposure

Exposure is most likely on Apple endpoints, mobile devices, watches, Apple TV devices, and older macOS systems that have not installed the fixed releases named by Apple. Highest concern is unmanaged or slow-patching fleets where users can install or run untrusted apps.

Exploitation context

The source bundle does not show CISA KEV listing or other evidence of active exploitation. The CVSS vector indicates exploitation is local and requires user interaction, but no prior privileges. Kernel privilege execution makes successful exploitation serious despite the interaction requirement.

Researcher notes

The bundle identifies an out-of-bounds write fixed through improved input validation but does not name a specific kernel component or provide exploit details. Validation should focus on version state, advisory mapping, and whether exposed users can execute untrusted apps.

Mitigation direction

  • Update affected Apple devices to the fixed releases listed by Apple.
  • Prioritize unmanaged devices and systems below iOS 15.6, iPadOS 15.6, or macOS 12.5.
  • Apply macOS Big Sur 11.6.8 or Security Update 2022-005 Catalina where relevant.
  • Apply watchOS 8.7 and tvOS 15.6 where those platforms are in scope.
  • Review Apple advisories for any platform-specific deployment guidance.

Validation and detection

  • Inventory Apple device OS versions across managed and unmanaged fleets.
  • Confirm devices meet or exceed the Apple fixed versions listed in the advisories.
  • Check MDM compliance reports for pending or failed operating system updates.
  • Identify devices allowing untrusted app installation or sideloading paths.
  • Track exceptions where legacy devices cannot receive the fixed release.
