Analysis

Impact

A use‑after‑free condition in Google Chrome's HTML5 Canvas implementation, present in versions earlier than 150.0.7871.47, allows a remote attacker to execute arbitrary code within the browser sandbox through a crafted HTML page. This memory‑corruption flaw (CWE‑416) exploits a freed memory reference and can be triggered without user interaction beyond opening the malicious page.

Affected Systems

All users running Google Chrome prior to version 150.0.7871.47 are affected. The June 2026 stable channel update that shipped version 150.0.7871.47 or later includes the patch, eliminating the issue. No other vendors or product lines were impacted.

Risk and Exploitability

The CVE has a CVSS score of 8.8, indicating high severity, while its EPSS score is less than 1 %, suggesting a low current exploitation probability. It is not listed in the CISA KEV catalog. The likely attack vector is a malicious web page that the victim visits, where a single click or page load can trigger the use‑after‑free path and execute code within the sandbox.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Upgrade Google Chrome to version 150.0.7871.47 or later to apply the vendor‑supplied memory‑corruption fix.
If an upgrade is delayed, disable or restrict Canvas usage in Chrome via enterprise policy or flag settings to mitigate the use‑after‑free condition.
Implement automatic Chrome updates and enforce stricter web‑filtering rules to prevent users from visiting malicious web pages until the patch is deployed.
