CVE-2022-30703
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTrend Micro Security 2021 and 2022 (Consumer) is vulnerable to an exposed dangerous method vulnerability that could allow an attacker to obtain access to leaked kernel addresses and disclose sensitive information. This vulnerability could also potentially be chained for privilege escalation.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceTrend Micro Security 2021 and 2022 (Consumer) contains an exposed dangerous method vulnerability that allows unprivileged attackers to leak kernel addresses from memory, exposing sensitive information. This information disclosure could enable privilege escalation when chained with other vulnerabilities.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Trend Micro Security is installedCheck for Trend Micro Security installation via program list (Windows: Add/Remove Programs or Settings > Apps), or look for Trend Micro processes/services running (e.g., tmcc, tmtisd, tmactmon).Affected if Trend Micro Security consumer product is installed on the system.
-
Identify the installed versionOpen Trend Micro Security main UI and navigate to Help > About, or right-click the tray icon and select 'About'. Note the exact version number displayed (e.g., 2021 or 2022).Affected if The installed version is exactly 2021 or exactly 2022.
-
Verify it is the Consumer editionConfirm through the product name or license type that this is the Consumer version, not enterprise/server editions (enterprise versions have different naming such as 'OfficeScan' or 'Deep Security').Affected if The product is Trend Micro Security 2021 Consumer or Trend Micro Security 2022 Consumer.
-
Check for exposed kernel communication interfaceInspect the Trend Micro Security driver/services (such as tmcomm driver or tmactmon) for exposed interfaces that could leak kernel memory addresses. This requires examining running services and their exposed IPC mechanisms.Affected if The product exposes an interface allowing unprivileged access to kernel address information.
The system is affected if Trend Micro Security Consumer version 2021 or 2022 is installed and the exposed dangerous method interface is present and accessible to unprivileged users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches or upgrade to a fixed version of Trend Micro Security. As an interim measure, restrict access to the vulnerable component and monitor for exploitation attempts.
