AI Analysis

Impact

A use‑after‑free flaw in the Turbolev component of Google Chrome allows a remote attacker to execute arbitrary code inside the sandbox by serving a specially crafted HTML page. The vulnerability can be triggered without authentication and gives the attacker full control of the browser process within the sandbox, potentially leading to additional compromise of the host system.

Affected Systems

Google Chrome desktop browsers running versions before 156.0.8078.47 are impacted. Any installation of Chrome that has not yet applied the 156.0.8078.47 release is vulnerable.

Risk and Exploitability

The CVSS score of 8.8 classifies this flaw as a high‑severity risk. The EPSS score is < 1%, indicating a very low but non‑zero probability of exploitation, and the vulnerability is not listed in CISA KEV. The likely attack vector is a crafted web page viewed in the affected browser, implying that a remote attacker can exploit the flaw from outside the network.

OpenCVE Recommended Actions

  • Update Chrome to version 156.0.8078.47 or later
  • Ensure that auto‑update is enabled so future browser security patches are applied automatically
  • If updating immediately is infeasible, restrict user access to the vulnerable browser or disable all extensions until the patch is installed
