AI Analysis

Impact

A use‑after‑free vulnerability exists in the Media component of Google Chrome versions prior to 155.0.8059.39. When a crafted HTML page is loaded, the flaw can allow a remote attacker to execute arbitrary code inside Chrome’s sandbox environment. This is a memory management error classified as CWE‑416.

Affected Systems

The issue affects Google Chrome across all platforms that include the Media module. Any version of Chrome before 155.0.8059.39 is impacted. Users should verify the installed version and upgrade accordingly.

Risk and Exploitability

The CVSS score of 8.8 indicates a high severity impact. Because EPSS data is not available and the vulnerability is not listed in the CISA KEV catalog, the exploitation probability is uncertain. The remote attack vector—via a crafted HTML page—means any browser that can be instructed to open a malicious page can be targeted, allowing the attacker to trigger the use‑after‑free bug and execute arbitrary code within the Chrome sandbox.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Google Chrome to version 155.0.8059.39 or later to apply the vendor fix.
  • Configure or enforce a strict Content Security Policy that disallows inline scripts and restricts script origins to trusted domains. This reduces the chance that a crafted page can deliver malware.
  • Verify that Chrome Sandbox features remain enabled and that any custom browser extensions or policies do not disable sandbox isolation.
