Published Aug 25, 2026 CVSS 3.1 · 7.7 High EPSS < 1% KEV · Not listed
Description
Use after free in UI in Google Chrome prior to 152.0.7977.65 allowed a local attacker who had compromised the renderer process to execute arbitrary code outside the sandbox via a local program. (Chromium security severity: Medium)

Analysis

AI-generated

Technical impact

A use‑after‑free bug in the Chrome user interface allows a local attacker who has already compromised the renderer process to execute arbitrary code outside the browser’s sandbox. The flaw is triggered when the renderer performs an invalid memory dereference after freeing the UI object, giving the attacker control of the process.

Affected Systems

The vulnerability affects Google Chrome on all platforms before version 152.0.7977.65. Users running any earlier Chrome release are exposed.

Risk and Exploitability

Because the attack requires local access to a compromised renderer process, the attack surface is limited to the victim’s machine. The EPSS score of <1% indicates a very low exploitation probability. The CVSS score of 7.7 indicates medium severity, and no exploitation data or KEV listing is available at this time. Nonetheless, the possibility of arbitrary code execution warrants immediate attention and patching.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Chrome to version 152.0.7977.65 or newer.
  • Verify that the Chrome sandbox remains active for all processes.
  • If an update cannot be applied immediately, restrict the renderer process by running Chrome in a low‑privilege or separate user account to limit potential damage.
