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

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.

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.

Remote code execution in Google Chrome prior to version 146.0.7680.178 exploits object corruption in the V8 JavaScript engine, allowing attackers to execute arbitrary code within the Chrome sandbox via a specially crafted HTML page. The vulnerability affects all Chrome versions below the patched release and carries a High Chromium security severity rating.

Remote code execution via heap buffer overflow in Google Chrome's GPU component affects all versions prior to 146.0.7680.178, allowing attackers to execute arbitrary code by crafting malicious HTML pages. The vulnerability requires only a remote attacker with no special privileges or user authentication; users need only visit a compromised or attacker-controlled website. No CVSS score was assigned by NVD, though Chromium classified it as High severity. Patch availability confirmed from vendor.

Remote code execution in ANGLE (Almost Native Graphics Layer Engine) within Google Chrome on macOS prior to version 146.0.7680.178 allows unauthenticated remote attackers to execute arbitrary code by crafting a malicious HTML page that triggers a heap buffer overflow. This vulnerability affects all Chrome versions below the patched release and poses an immediate risk to macOS users who visit compromised or malicious websites.

Remote code execution in Google Chrome on Android via use-after-free vulnerability in Web MIDI allows unauthenticated remote attackers to execute arbitrary code through a crafted HTML page. The vulnerability affects Chrome versions prior to 146.0.7680.178 and carries high severity per Chromium's security classification. A vendor-released patch is available.

Remote code execution in Google Chrome prior to 146.0.7680.178 allows unauthenticated remote attackers to execute arbitrary code within the Chrome sandbox via a crafted HTML page exploiting a use-after-free vulnerability in the WebCodecs component. The vulnerability affects all versions before the patched release and has been addressed by Google with a vendor-released patch; no public exploit code or active exploitation has been confirmed at the time of analysis.
