CVE-2026-3542
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 · uneditedInappropriate implementation in WebAssembly in Google Chrome prior to 145.0.7632.159 allowed a remote attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity: High)
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 memory safety vulnerability in Google Chrome's WebAssembly implementation allows a remote attacker to perform out-of-bounds memory access via a specially crafted HTML page. This inappropriate implementation flaw enables the attacker to read or write memory outside the boundaries of allocated WebAssembly buffers.

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.
-
Locate Chrome installation pathOn Windows, check C:\Program Files\Google\Chrome\Application\chrome.exe or C:\Program Files (x86)\Google\Chrome\Application\chrome.exe. On macOS, check /Applications/Google Chrome.app. On Linux, check /usr/bin/google-chrome or /opt/google/chrome/google-chromeAffected if Chrome is installed on the system
-
Determine installed Chrome versionOpen Chrome and navigate to chrome://version, or from command line run 'google-chrome --version' on Linux/macOS, or right-click chrome.exe > Properties > Details tab on WindowsAffected if The displayed version number is lower than 145.0.7632.159
-
Verify WebAssembly is enabledIn Chrome, go to chrome://flags and search for 'WebAssembly'. Confirm the flag is not disabled (default state is enabled)Affected if WebAssembly is enabled (default) - this is required for the vulnerability to be exploitable
-
Confirm user can be tricked into visiting malicious pagesReview whether users have unrestricted web browsing capability or can open arbitrary HTML files in ChromeAffected if Users can open untrusted HTML pages in Chrome - this is the attack vector
You are affected if Google Chrome version is lower than 145.0.7632.159 and users can be persuaded to open a crafted HTML page in the browser.

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.
dbcve · scoped145.0.7632.159145.0.7632.160
Update Google Chrome to version 145.0.7632.159 or later to remediate this vulnerability. Users should avoid visiting untrusted websites until the browser is updated.
Chromium 145.0.7632.159 or later (or the corresponding stable release for your Chromium-based browser that includes this security fix)
- 1. Identify the Chromium-based browser in use (Chrome, Edge, Brave, Opera, etc.)
- 2. Check the current browser version in the application's Help > About section
- 3. If the browser version is below 145.0.7632.159 (or 145.0.7632.160 for the second fixed version), download and install the latest version from the official vendor website
- 4. Alternatively, if using Google Chrome, navigate to chrome://settings/help to check for updates and install any available updates
- 5. Restart the browser after the update is applied
- 6. Verify the version has been updated to 145.0.7632.159 or higher
