AI Analysis

Impact

A use‑after‑free flaw exists in Chrome’s Autofill component on Windows, and it can be triggered by a crafted HTML page when a user is persuaded to perform specific UI gestures. The flaw can corrupt heap memory, potentially allowing an attacker to execute arbitrary code on the affected machine. The description explicitly states that the vulnerability is of critical severity, but the exact downstream exploits are not enumerated in the official advisory.

Affected Systems

Google Chrome running on Windows, versions prior to 149.0.7827.103. Users of older Chrome builds are impacted until they upgrade to 149.0.7827.103 or later.

Risk and Exploitability

The flaw is rated as high severity with a CVSS score of 7.5, but it is not yet listed in the CISA KEV catalog. The required attack vector involves a remote attacker delivering a specially crafted HTML page and convincing a user to interact with it, so the exploit depends on user activity but can still be automated through phishing or malicious sites. Due to the high severity of the use‑after‑free, the risk, if the conditions are met, is significant.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Chrome to version 149.0.7827.103 or later, which removes the use‑after‑free flaw (CWE‑416) in Autofill.
  • In the absence of an immediate patch, disable the Autofill feature via Chrome’s enterprise policy to mitigate the CWE‑416 use‑after‑free vulnerability.
  • In an enterprise context, monitor and restrict sites that trigger UI gestures, whitelisting only trusted domains to reduce the CWE‑416 attack surface.
