CVE-2020-15603
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 · uneditedAn invalid memory read vulnerability in a Trend Micro Secuity 2020 (v16.0.0.1302 and below) consumer family of products' driver could allow an attacker to manipulate the specific driver to do a system call operation with an invalid address, resulting in a potential system crash.
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 · high confidenceA kernel-mode driver in Trend Micro Security 2020 (v16.0.0.1302 and below) contains an invalid memory read vulnerability allowing attackers to manipulate the driver to perform system call operations with invalid memory addresses, resulting in system crashes (denial of service).

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.
-
Verify Trend Micro Security 2020 product is installedOpen Programs and Features in Windows Control Panel and look for any of these products: Trendmicro Antivirus+, Trendmicro Internet Security, Trendmicro Maximum Security, or Trendmicro Premium Security (2020 versions)Affected if Any of these four Trend Micro 2020 products appear in the installed programs list
-
Check the installed version numberRight-click the installed Trend Micro program in Programs and Features and select Properties, then view the Details tab to find the Version field. Alternatively, locate the main program executable (typically in C:\Program Files\Trend Micro\) and check its file versionAffected if The version number displayed is 16.0.1302 or lower (versions up to and including 16.0.1302 are vulnerable)
-
Identify the kernel-mode driver componentOpen an elevated command prompt and run 'sc query type= driver' to list kernel drivers, or check the Trend Micro installation directory (usually C:\Program Files\Trend Micro\) for driver files such as tmcomm.sys, tmdi.sys, or tmlwf.sysAffected if A Trend Micro kernel driver file exists on the system and corresponds to the vulnerable product version
-
Confirm the driver version matches vulnerable releaseRight-click the driver file (if found), select Properties, and check the File Version on the Details tab. Compare this version to the affected range (16.0.0.1302 and below)Affected if The driver file version is 16.0.0.1302 or below, indicating the vulnerable driver is in use
A user is affected if they have any of the four Trend Micro 2020 products installed with version 16.0.1302 or lower, which contains the vulnerable kernel-mode driver.

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 dataUpgrade Trend Micro Security 2020 to a version higher than 16.0.0.1302, or apply the vendor-supplied patch to remediate the vulnerable driver.
