AI Analysis

Impact

The vulnerability is a type confusion flaw in the handling of WebFonts that can lead to memory corruption. A malicious webpage can trigger this flaw, enabling a remote attacker to execute arbitrary code inside the Chrome sandbox when the page is rendered.

Affected Systems

Affected systems are installations of Google Chrome lower than version 156.0.8078.47. Any user who may load a crafted HTML page in that browser is at risk.

Risk and Exploitability

The CVSS score of 8.8 indicates a high severity risk. The EPSS score is < 1%, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in CISA's KEV catalog, so no widespread exploitation has been reported. Exploitation requires a remote attacker to serve a specially crafted HTML file or exploit a site the user visits; the attack vector is inferred to be remote via webpage content.
