Analysis

AI-generated

Technical impact

An uninitialized resource in the Dawn rendering engine of Google Chrome on Android allows a remote attacker to read memory contents outside the browser sandbox when a crafted HTML page is rendered. The flaw enables a data‑leak attack that can expose sensitive information. The weakness is categorized as CWE‑908 – Uninitialized Resource.

Affected Systems

Google Chrome for Android versions prior to 154.0.8037.92 are affected. Users of any device running these versions of Chrome should upgrade to the latest stable release, which includes the necessary memory‑safety fix.

Risk and Exploitability

The CVSS score of 4.7 indicates moderate overall risk, and the EPSS score is not available. The vulnerability is not listed in CISA’s KEV catalog, but Chromium’s own assessment labels it as High. The likely attack vector is remote, triggered by a maliciously crafted HTML page opened in Chrome. Exploitation requires no additional privileges; a user simply visits the HTML content, after which the attacker can read memory outside the sandbox.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Chrome to version 154.0.8037.92 or later on all Android devices.
  • If an immediate update is not possible, mitigate exposure by restricting untrusted HTML content through a sandboxed browsing mode or by disabling automatic loading of external content.
  • Continuously monitor Chrome’s release notes for future security updates and apply them promptly.
