Impact

This vulnerability is a use‑after‑free flaw in Chrome's Search component. A remote attacker who can compromise the renderer process can trigger the flaw by serving a crafted HTML page, resulting in execution of arbitrary code outside the sandbox. The attacker could thus gain elevated privileges on the host system.

Affected Systems

Google Chrome versions prior to 156.0.8078.47 on desktop operating systems—including Windows, macOS, and Linux—are affected. The issue is specific to the Chrome browser and does not impact other Google products.

Risk and Exploitability

The CVSS score of 8.8 indicates high severity, and the EPSS score of < 1% suggests a very low exploitation probability. The vulnerability is not listed in the CISA KEV catalog. The likely attack vector is a crafted HTML page served by an adversary and opened in the victim's Chrome browser, leveraging the Search feature to trigger memory corruption.
