CVE-2026-14422 Overview
CVE-2026-14422 is an out-of-bounds read and write vulnerability in Tint, the WebGPU shader translator used by Google Chrome. The flaw affects Chrome versions prior to 150.0.7871.46. A remote attacker can trigger out-of-bounds memory access by convincing a user to load a crafted HTML page. Chromium security engineering rated the underlying issue as High severity. Successful exploitation can corrupt renderer process memory, potentially leading to code execution within the sandbox or information disclosure across WebGPU buffers.
Critical Impact
A crafted web page can trigger out-of-bounds memory reads and writes in the Chrome renderer, enabling memory corruption and potential sandboxed code execution.
Affected Products
- Google Chrome versions prior to 150.0.7871.46
- Chromium-based browsers embedding vulnerable Tint/WebGPU components
- Desktop channels for Windows, macOS, and Linux prior to the fixed Stable release

Technical Details for CVE-2026-14422
Vulnerability Analysis
Tint is the shader translator that converts WebGPU Shading Language (WGSL) into backend-specific shader code inside Chrome's GPU pipeline. The vulnerability allows both out-of-bounds reads and out-of-bounds writes during shader processing. An attacker delivers a crafted HTML page that instantiates WebGPU and submits malformed shader input. Tint mishandles boundary conditions while parsing or transforming the shader intermediate representation. This results in memory access outside the intended buffer region within the renderer or GPU process.
Out-of-bounds writes are particularly dangerous because they permit adversary-controlled data to overwrite adjacent memory. Combined with the read primitive, an attacker can leak pointers to bypass Address Space Layout Randomization (ASLR) and stage a full memory corruption chain.
Root Cause
The root cause is improper bounds validation inside Tint when handling attacker-supplied shader constructs. Insufficient length or index checks allow operations to access memory beyond the allocated region. Details are tracked in the Chromium Issue Tracker Entry.
Attack Vector
Exploitation requires the victim to visit a malicious or compromised web page in a vulnerable Chrome build. No authentication is required, and no user interaction beyond page navigation is needed. The attacker delivers WGSL shader payloads through the WebGPU API to trigger the out-of-bounds access.
No public proof-of-concept code is available. See the Google Chrome Update Announcement for vendor guidance.
Detection Methods for CVE-2026-14422
Indicators of Compromise
- Unexpected Chrome renderer or GPU process crashes tied to tint or WebGPU stack frames
- Browsing history entries showing visits to untrusted domains that invoke WebGPU
- Endpoint telemetry showing child processes spawned by chrome.exe following renderer instability
Detection Strategies
- Inventory Chrome installations and flag any endpoint running a version below 150.0.7871.46
- Correlate crash dump artifacts referencing Tint or WGSL translation with recent browsing activity
- Monitor egress web traffic to newly registered or low-reputation domains delivering WebGPU content
Monitoring Recommendations
- Enable browser telemetry forwarding to a central log platform for renderer crash visibility
- Track Chrome version compliance across managed fleets using enterprise management policies
- Alert on repeated GPU process termination events across multiple hosts, which may indicate active exploitation attempts
How to Mitigate CVE-2026-14422
Immediate Actions Required
- Update Google Chrome to version 150.0.7871.46 or later on all supported platforms
- Restart the browser after update to ensure the patched Tint component is loaded
- Push the update through enterprise management tools such as Chrome Browser Cloud Management or Group Policy
Patch Information
Google released the fix in the Stable channel update documented in the Google Chrome Update Announcement. Chromium-based browser vendors should incorporate the corresponding upstream Tint patch and ship updated builds to their users.
Workarounds
- Disable WebGPU via the chrome://flags/#enable-unsafe-webgpu and related flags where feasible until patching completes
- Restrict access to untrusted websites through enterprise web filtering policies
- Use browser isolation for high-risk users who cannot immediately update
# Verify Chrome version on Linux endpoints
google-chrome --version
# Windows: query installed version via registry
reg query "HKLM\SOFTWARE\Google\Chrome\BLBeacon" /v version
