Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in the Autofill feature of Google Chrome versions before 151.0.7922.72. A use-after-free occurs when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution. In this case, a remote attacker could exploit this by crafting a malicious HTML page to trigger the flaw.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 151.0.7922.72. To detect it, check your Chrome version by running chrome://version/ in the browser address bar. If your version is below 151.0.7922.72, the system is vulnerable. Update Chrome immediately to version 151.0.7922.72 or later.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to execute arbitrary code on your system. Since it occurs inside a sandbox, the impact is somewhat limited, but successful exploitation could still lead to data theft, installation of malware, or unauthorized system access depending on the attacker's goals.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it involves a technical flaw in Google Chrome's Autofill feature. Compliance impacts would depend on how the vulnerability is exploited in a specific environment or system handling regulated data.

Mitigation Strategies

Update Google Chrome to version 151.0.7922.72 or later to address the use-after-free vulnerability in Autofill.
