AI Analysis

Impact

A use‑after‑free fault in Chrome’s media processing component allows an attacker to execute arbitrary code inside the browser’s sandboxed process. The flaw is identified as CWE‑416 and can lead to code execution with the limited privileges of the sandbox. If exploited, the attacker may gain the ability to carry out further privileged actions within the web page’s context or leverage the sandbox to escape isolation.

Affected Systems

All versions of Google Chrome released before 155.0.8059.79 are affected.

Risk and Exploitability

The CVSS score of 8.8 indicates a high severity while the EPSS score of less than 1% suggests that active exploitation is currently low. Based on the description, it is inferred that the likely attack vector is a remote user visiting a specially crafted HTML page that triggers the use‑after‑free during media handling. The flaw is not listed in the CISA KEV catalog, implying it has not yet been widely exploited.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Chrome to version 155.0.8059.79 or later on all affected systems.
  • If an upgrade cannot be performed immediately, restrict media processing by disabling unnecessary media features through command‑line flags or group policy and enforce a restrictive Content Security Policy that blocks arbitrary scripts in media contexts.
  • Continue to use the browser sandbox and site isolation features, monitor browser logs for abnormal activity, and keep the operating system and other software up to date.
