Use-after-free in Google Chrome Forms

IdentifiersCVE-2026-6316CWE-416· Use After Free

CVE-2026-6316 is a high-severity use-after-free vulnerability in the Forms component of Google Chrome. The flaw affects Chrome versions prior to 147.0.7727.101 and arises from a dangling-pointer condition in form-related object handling, where code can reference a Forms-related object after its memory has already been freed. A remote attacker can trigger the bug by causing a victim to load a crafted HTML page, leading to arbitrary code execution within the Chrome renderer sandbox.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to execute arbitrary code inside the Chrome sandboxed renderer process. While the immediate code-execution context is confined by the browser sandbox, the vulnerability still provides a strong foothold for further exploitation and could be chained with a separate sandbox-escape vulnerability to achieve broader compromise. The CVSS v3.1 vector provided in the source indicates high confidentiality, integrity, and availability impact.

Mitigation

If you can’t patch tonight, do this now.

Apply the vendor patch as the primary mitigation. Until patching is complete, reduce exposure by limiting access to untrusted websites, blocking or filtering phishing-delivered links, and using browser isolation or application sandboxing controls where available. Because exploitation requires a victim to visit a crafted HTML page, user-awareness controls and web filtering may reduce risk, but they are not substitutes for updating.

Remediation

Patch, then assume compromise.

Update Google Chrome to version 147.0.7727.101 or later. The content indicates fixed Stable Channel builds include 147.0.7727.101 for Linux and 147.0.7727.101/.102 variants for Windows and macOS. Organizations using Chromium-based browsers such as Microsoft Edge, Brave, Opera, or Vivaldi should ensure those vendors have incorporated the upstream Chromium fix and deploy the corresponding updated browser versions.
