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 · unedited
Anti-Cheat Expert's Windows kernel module "ACE-BASE.sys" version 1.0.2202.6217 does not perform proper access control when handling system resources. This allows a local attacker to escalate privileges from regular user to System or PPL level.

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 confidence

The ACE-BASE.sys kernel driver (version 1.0.2202.6217) from Anti-Cheat Expert fails to enforce proper access control checks when processing system resource requests, enabling a local authenticated attacker to escalate privileges from a standard user account to System or PPL (Protected Process Light) level.

MitigationUpdate ACE-BASE.sys to a patched version provided by Anti-Cheat Expert, or uninstall the software if no patch is available. Since this is a vendor-specific kernel driver vulnerability, no workarounds are recommended.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate ACE-BASE.sys driver file
    Search for ACE-BASE.sys on the system using: Get-ChildItem -Path C:\ -Recurse -Filter ACE-BASE.sys -ErrorAction SilentlyContinue 2>$null or check typical driver locations like C:\Windows\System32\drivers\ and the Anti-Cheat Expert installation folder.
    Affected if The file ACE-BASE.sys is found on the system.
  2. Verify driver file version
    If the file is found, right-click the file, select Properties, then go to the Details tab to view the File Version. Alternatively, use PowerShell: (Get-Item 'C:\path\to\ACE-BASE.sys').VersionInfo.FileVersion
    Affected if The file version matches exactly 1.0.2202.6217, indicating the vulnerable version.
  3. Check if driver is loaded
    Run in PowerShell: driverquery /v | FindStr 'ACE-BASE' or check the Windows registry under HKLM\SYSTEM\CurrentControlSet\Services for an ACE-BASE entry.
    Affected if The driver is listed as loaded or registered as a service on the system.
  4. Confirm Anti-Cheat Expert installation
    Check installed programs via PowerShell: Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, InstallLocation | Where-Object {$_.DisplayName -like '*Anti-Cheat*' -or $_.DisplayName -like '*ACE*'}.
    Affected if Anti-Cheat Expert software is installed on the system.
  5. Compare version to affected range
    If version information is obtained from any of the above checks, compare it against the known vulnerable version 1.0.2202.6217. Treat any version at or below this as potentially affected if no later patched version is confirmed.
    Affected if The installed version is 1.0.2202.6217 or lower, and no explicit patched version is confirmed.

A system is affected if ACE-BASE.sys driver version 1.0.2202.6217 from Anti-Cheat Expert is present and loaded on the machine, enabling a local authenticated attacker to escalate privileges.
