Use-after-free in WebRTC in Google Chrome

IdentifiersCVE-2026-4445CWE-416· Use After Free

CVE-2026-4445 is a high-severity use-after-free vulnerability in the WebRTC component of Google Chrome. According to the provided content, affected versions are Google Chrome prior to 146.0.7680.153. The flaw can be triggered by a remote attacker via a crafted HTML page, leading to heap corruption. As a use-after-free condition, the vulnerability arises when memory is accessed after it has been freed, which can result in memory corruption and potentially attacker-controlled execution flow depending on heap state and exploit reliability.

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 may allow a remote, unauthenticated attacker to corrupt heap memory in the browser process by convincing a user to load a malicious HTML page. The provided content indicates that Chrome vulnerabilities in this update set could result in arbitrary code execution, denial of service, or information disclosure, and specifically notes that memory corruption flaws in components including WebRTC could enable remote code execution.

Mitigation

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

Apply the vendor update as the primary mitigation. Until patching is completed, reduce exposure by limiting use of untrusted websites and potentially malicious HTML content, and by using browser isolation or sandboxing controls where available. No vulnerability-specific workaround is provided in the supplied content.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome/Chromium to version 146.0.7680.153 or later. The provided content states that Chrome Stable fixes were released in versions 146.0.7680.153 and 146.0.7680.154 for Windows and macOS, and 146.0.7680.153 for Linux. Systems running versions prior to 146.0.7680.153 should be updated to a fixed release.
