CVE-2025-13032
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 · uneditedDouble fetch in sandbox kernel driver in Avast/AVG Antivirus <25.3 on windows allows local attacker to escalate privelages via pool overflow.
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 confidenceA double-fetch race condition vulnerability in the sandbox kernel driver of Avast/AVG Antivirus for Windows (versions prior to 25.3) allows a local authenticated attacker to escalate privileges through a pool overflow exploit. The double-fetch occurs when the kernel driver reads the same memory location multiple times, enabling an attacker to manipulate timing to trigger the pool overflow and achieve arbitrary code execution at kernel level.

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 Avast Antivirus is installedCheck for Avast Antivirus installation via Programs and Features, or look for Avast executable files in typical installation directories (e.g., C:\Program Files\Avast).Affected if Avast Antivirus is present on the system.
-
Determine installed Avast versionOpen Avast Antivirus, go to Menu > Settings > About, or right-click the Avast icon in the system tray and select 'About Avast'. Alternatively, check the program's properties in Programs and Features.Affected if Unable to determine version or version is displayed.
-
Compare version against affected rangeCompare your installed version number to the affected range (versions prior to 25.3). Note the full version string (e.g., 24.x, 25.x).Affected if Installed version is less than 25.3 (e.g., 24.10.x, 24.5.x, etc.).
-
Identify if sandbox kernel driver is activeCheck for Avast sandbox-related kernel drivers or services. In an elevated command prompt, run 'sc query' or check Device Manager for Avast sandbox drivers. The vulnerable component is the sandbox kernel driver.Affected if Avast sandbox kernel driver is present and loaded on the system.
If Avast Antivirus is installed with a version prior to 25.3 and the sandbox kernel driver is active, the environment is affected by CVE-2025-13032.
