AI Analysis

Impact

A use‑after‑free bug in Chrome’s Media component allows a crafted HTML page to be loaded, causing the browser to execute arbitrary code within the sandbox. The lack of proper memory protection lets attackers take control of the Media subsystem, potentially running malicious code with the privileges granted to the sandboxed process.

Affected Systems

The vulnerability affects Google Chrome versions prior to 155.0.8059.39 on desktop platforms. Any user who has an older install of Chrome and visits a maliciously constructed web page is at risk.

Risk and Exploitability

Chrome’s CVSS score of 8.8 indicates a high severity. No EPSS data is available, and the issue is not listed in the CISA KEV catalog, suggesting that the attack vector is primarily via crafted web content. An attacker needs only the victim to open a malicious page, after which code can execute inside the sanitized sandbox. The potential impact includes full system compromise if the sandbox or its confines are otherwise exploitable by other elevating mechanisms.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade the browser to Chrome 155.0.8059.39 or later, which contains the fixed Media component.
  • If upgrading is not immediately possible, restrict users from loading untrusted web pages by configuring Chrome’s site‑wide sandbox policy or using a web‑filtering solution to block domains known to serve malicious content.
  • Continue to monitor user activity on affected systems for signs of sandbox escapes or anomalous processes, and keep the browser up‑to‑date as soon as patches become available.
