AI Analysis

Impact

A use‑after‑free flaw in Chrome’s WebRTC component allows a remote attacker to execute arbitrary code inside the browser sandbox by serving a crafted HTML page. The vulnerability is disclosed as a classic memory corruption error (CWE‑416). This flaw can compromise the confidentiality and integrity of data processed by the browser and potentially expose the system to additional attacks that exfiltrate or tamper with information.

Affected Systems

Google Chrome browsers with builds earlier than 155.0.8059.39 are affected. The flaw is fixed in version 155.0.8059.39 and all subsequent releases of Chrome.

Risk and Exploitability

The CVSS v3.1 score of 8.8 indicates high severity, and the EPSS score is not available, so the public probability of exploitation is unknown. The vulnerability is not listed in the CISA KEV catalog. Attackers can exploit the flaw from a remote web page that a user visits or from untrusted web resources that the browser loads, allowing code execution within the sandboxed process.
