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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 UI component of Google Chrome versions before 150.0.7871.182. It occurs when a program tries to use memory that has already been freed, potentially leading to heap corruption. An attacker could exploit this by tricking a user into performing specific UI gestures on a crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 150.0.7871.182. To detect it, check your Chrome version by running chrome://version/ in the browser. If your version is below 150.0.7871.182, the system is vulnerable. Update Chrome immediately to the latest version to mitigate the risk.

Impact Analysis

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's UI that could allow remote attackers to exploit heap corruption via crafted HTML pages. Such vulnerabilities may lead to unauthorized data access or manipulation, which could violate GDPR's data protection requirements or HIPAA's safeguards for protected health information if exploited in systems handling such data.

Mitigation Strategies

Update Google Chrome to version 150.0.7871.182 or later to address the use after free vulnerability in the UI component.
