AI Analysis

Impact

The flaw is a classic buffer overflow in the Tint component used by Google Chrome on Android. It can be triggered by a specially crafted HTML page and allows a remote attacker to execute arbitrary code outside the usual browser sandbox; it is identified as CWE-122. The impact is the potential compromise of the entire device, including access to local data and execution of system‑level commands.

Affected Systems

All Android installations of Google Chrome running a build prior to 154.0.8037.57 are affected. The browser must be updated to 154.0.8037.57 or later to mitigate the issue.

Risk and Exploitability

The CVSS score of 9.6 indicates that the vulnerability has a very high potential for exploitation, and the EPSS score is not provided. The flaw is listed as not included in the CISA KEV catalog. The likely attack vector is a remote attacker delivering a crafted HTML page to a victim’s Chrome browser on Android. Once the overflow is triggered, the attacker can escape the sandbox and execute code with the privileges of Chrome, possibly escalating to system level.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Chrome on all Android devices to version 154.0.8037.57 or newer, which contains the fix for the buffer overflow.
  • If an immediate update is not feasible, configure device management or network policies to block or restrict access to potentially malicious web pages that could exploit the Tint component.
  • When the patch cannot be applied promptly, consider disabling the Tint feature via Chrome experimental flags or enterprise policies to reduce the risk until the update is available.
