CVE-2026-41157
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 · uneditedA web page that contains unusual WebGPU content loaded into the GPU GLES render process and can trigger an out-of-bound write in the GPU user-space driver, leading to memory corruption and possible browser/GPU process crash. The software computes a required memory size from untrusted input, but integer overflow can produce a value smaller than needed. Subsequent write operations may then occur past the intended memory boundary, corrupting adjacent memory and causing process instability or termination.
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 vulnerability in the GPU GLES render process allows a malicious WebGPU page to trigger an integer overflow when calculating required memory size from untrusted input. The overflow produces a value smaller than actually needed, causing subsequent write operations to extend past allocated buffer boundaries, resulting in memory corruption and potential process crash.

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 WebGPU is enabled in the browserNavigate to chrome://flags or about:flags and search for 'WebGPU' or check if the WebGPU API is accessible via browser console with: navigator.gpu !== undefinedAffected if WebGPU is enabled and the browser version contains the vulnerability
-
Confirm GPU rendering is activeOpen chrome://gpu and verify that 'GPU process' shows as enabled, and check the 'Graphics Feature Status' for GLES or Vulkan accelerationAffected if GPU rendering is enabled with GLES backend
-
Determine browser versionOpen chrome://settings/help or go to Help > About in the browser menu to view the full version number (e.g., Chrome 120.x.x.x)Affected if The installed version falls within the vulnerable range and no security patch has been applied
-
Review GPU process crash logsOpen chrome://crashes or check system event logs (Windows Event Viewer under Application logs, or ~/.cache/chromium/Crashpad/reports on Linux) for recent GPU process crashes with memory corruption indicatorsAffected if Recent crashes involve the GPU process with faulting address or buffer overflow patterns
The environment is likely affected if the browser has WebGPU enabled, uses GLES GPU rendering, and the installed version has not been patched to address the integer overflow in GPU memory allocation for WebGPU content.

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 dataApply vendor patches/updates for the affected browser or GPU software once released. Until then, consider disabling WebGPU support in browser settings or restricting access to untrusted WebGPU content to reduce attack surface.
