Exploitability

CWE

KEV

CWE ID	Description
CWE-79	The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Google Chrome's ReadingMode feature. It occurs when a program tries to use memory after it has been freed, potentially allowing a remote attacker to execute arbitrary code within the browser's sandbox 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 or chrome://version in the browser. If your version is below 156.0.8078.47, the system is vulnerable.

Impact Analysis

An attacker could exploit this to run malicious code on your device, potentially stealing data, installing malware, or taking control of your browser session. Since it requires user interaction (visiting a crafted page), keeping cautious of unknown links is important.

Compliance Impact

This vulnerability is a use-after-free issue in Google Chrome's ReadingMode that could allow remote attackers to execute arbitrary code inside the sandbox. While it does not directly impact compliance with standards like GDPR or HIPAA, such vulnerabilities may lead to unauthorized data access or execution, which could violate data protection requirements if exploited.

Mitigation Strategies

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