CVE-2026-8534
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 · uneditedInteger overflow in GPU in Google Chrome on Linux and ChromeOS prior to 148.0.7778.168 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape 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.

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.
-
Identify the Chrome installationOpen terminal and run: google-chrome --version or chrome --version or /opt/google/chrome/google-chrome --versionAffected if Chrome is not installed or this command fails - not applicable to your environment
-
Confirm the operating systemRun: uname -a or cat /etc/os-release to verify Linux or ChromeOSAffected if The system is not Linux or ChromeOS - the CVE does not apply
-
Determine the installed Chrome versionRun: google-chrome --version and note the full version number (e.g., 148.0.7778.100)Affected if Version is lower than 148.0.7778.168 - your Chrome is affected by this vulnerability
-
Verify the GPU component is accessibleIn Chrome, navigate to chrome://gpu and check if GPU hardware acceleration is enabledAffected if GPU is disabled - the attack surface is reduced but the vulnerable code still exists in the binary
You are affected if Google Chrome version is lower than 148.0.7778.168 on Linux or ChromeOS, regardless of GPU settings, as the vulnerable integer overflow code exists in the GPU component regardless of whether it is actively used.
Generated from the published advisory. Verify against your own configuration.
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.
