CVE-2022-42827: An out-of-bounds write issue was addressed with improved bounds checking.

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 15.7.1 and iPadOS 15.7.1, iOS 16.1 and iPadOS 16. An application may be able to execute arbitrary code with kernel privileges. Apple is aware of a report that this issue may have been actively exploited..

Security readout for executives and security teams

Plain-English summary

This Apple iOS/iPadOS flaw could let a malicious application gain kernel-level control of a device. Apple fixed it in iOS 15.7.1, iPadOS 15.7.1, iOS 16.1, and iPadOS 16. Apple reported possible active exploitation, and CISA lists it in KEV.

Executive priority

Treat this as urgent mobile patching work, especially for users exposed to targeted attacks. Kernel-level code execution on phones can undermine device confidentiality and integrity, and KEV status raises business urgency.

Technical view

CVE-2022-42827 is a CWE-787 out-of-bounds write in iOS/iPadOS. The CVSS vector indicates local attack, low complexity, no privileges, required user interaction, and high confidentiality, integrity, and availability impact. Successful exploitation may execute arbitrary code with kernel privileges.

Likely exposure

Exposure is likely on iPhones and iPads running versions older than the fixed releases. The source bundle does not enumerate exact vulnerable version ranges, so validation should rely on installed OS version and Apple guidance.

Exploitation context

Apple stated it was aware of a report that the issue may have been actively exploited. CISA KEV inclusion supports treating exploitation as confirmed operational risk. Sources do not provide exploit mechanics, campaign details, or affected targets.

Researcher notes

The public sources identify impact and fixed versions but do not describe the vulnerable component, exploit chain, indicators, or complete affected-version matrix. Avoid assuming broader Apple platforms are affected without separate vendor evidence.

Mitigation direction

  • Update iPhones and iPads to Apple’s fixed releases or later.
  • Prioritize remediation for internet-facing staff, executives, and high-risk mobile users.
  • Use MDM to enforce minimum iOS and iPadOS versions.
  • Check Apple’s security pages for device-specific update guidance.
  • Apply CISA KEV handling requirements where applicable.

Validation and detection

  • Inventory iOS and iPadOS versions across managed devices.
  • Confirm devices run iOS 15.7.1, iPadOS 15.7.1, iOS 16.1, or later.
  • Review MDM compliance reports for stale or unmanaged devices.
  • Verify update status on personally enabled BYOD devices where policy allows.
  • Track exceptions until Apple-supported remediation is complete.

Out-of-bounds Write

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