CVE-2026-5281: Chrome WebGPU Use-After-Free PoC Toolkit & Scanner

Use-after-free in Google Chrome's Navigation component prior to version 146.0.7680.178 enables sandbox escape for attackers who have already compromised the renderer process, allowing them to potentially execute arbitrary code with elevated privileges via a malicious HTML page. Chromium rates this as high severity; patch availability confirmed from vendor.

Use-after-free in Chrome's compositing engine allows remote attackers who have compromised the renderer process to escape the sandbox via crafted HTML pages in Google Chrome prior to version 146.0.7680.178. This high-severity vulnerability requires prior renderer compromise but enables privilege escalation from the sandboxed renderer to system-level access, making it a critical sandbox bypass vector. Vendor-released patch addresses the issue in Chrome 146.0.7680.178 and later.

Use-after-free in Chrome's WebView on Android prior to version 146.0.7680.178 allows a remote attacker with a compromised renderer process to escape the sandbox via crafted HTML, potentially leading to arbitrary code execution outside the browser's security boundary. This vulnerability requires prior renderer compromise but eliminates a critical containment layer, classified as High severity by Chromium.

Remote code execution in Google Chrome prior to version 146.0.7680.178 allows attackers to execute arbitrary code within the Chrome sandbox via a specially crafted PDF file. The vulnerability exists in Chrome's PDF handling component and is caused by a use-after-free memory corruption flaw. Patch availability has been confirmed via vendor release, and the Chromium security team has classified this as High severity.

Remote code execution in Google Chrome prior to version 146.0.7680.178 via use-after-free vulnerability in the Dawn graphics library allows unauthenticated remote attackers to execute arbitrary code through a crafted HTML page. The vulnerability affects all Chrome versions below the patched release and carries high severity per Chromium's assessment.

Out-of-bounds read in WebCodecs component of Google Chrome prior to version 146.0.7680.178 allows remote attackers to read arbitrary memory contents via specially crafted HTML pages. The vulnerability affects all Chrome versions below the patched release and requires only HTML delivery (no authentication); exploitation could disclose sensitive data from the browser process memory, though the Chromium project assessed this as Medium severity.

Integer overflow in Google Chrome's Codecs component prior to version 146.0.7680.178 enables remote code execution and arbitrary memory read/write operations when a user visits a malicious HTML page. The vulnerability affects all versions before the patch release and requires no user interaction beyond visiting a crafted webpage. Chromium security team classified this as High severity; no public exploit code or active exploitation has been confirmed at the time of analysis.

Remote code execution in Google Chrome prior to version 146.0.7680.178 via use-after-free vulnerability in WebGL allows unauthenticated remote attackers to execute arbitrary code within the browser sandbox by delivering a crafted HTML page. The vulnerability is marked as High severity by Chromium security and a vendor-released patch is available.
