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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CWE-841	The product supports a session in which more than one behavior must be performed by an actor, but it does not properly ensure that the actor performs the behaviors in the required sequence.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in Google Chrome's Core component. It occurs when a program tries to use memory that has already been freed, potentially leading to arbitrary code execution. The attacker could exploit this by tricking a user into visiting a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 156.0.8078.47. To detect it, check your Chrome version by running chrome://version/ in the browser. If your version is below 156.0.8078.47, update immediately. No direct commands detect the exploit itself, but monitoring for unusual behavior or crashes may indicate exploitation.

Impact Analysis

If exploited, this vulnerability could allow a remote attacker to run malicious code on your device. This could lead to unauthorized access to your data, installation of malware, or other malicious activities while bypassing Chrome's sandbox protections.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code inside the sandbox via crafted HTML pages. Such arbitrary code execution could lead to unauthorized access to sensitive data, which may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.47 or later to address the use after free vulnerability in Core.
