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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 is a use-after-free vulnerability in Google Chrome's Animation component. It occurs when a program tries to use memory after it has been freed, potentially allowing an attacker to execute arbitrary code inside the browser's sandbox. The vulnerability is triggered by a crafted HTML page and affects Chrome versions prior to 156.0.8078.73.

Detection Guidance

I don't know

Detection typically requires checking the installed version of Google Chrome against the patched version (156.0.8078.73). Use commands like 'google-chrome --version' or check via package managers like 'apt list --installed | grep chrome'.

Impact Analysis

An attacker could exploit this to run malicious code on your device through a specially designed website. Since it allows code execution inside the sandbox, it may bypass some security restrictions, potentially leading to data theft, malware installation, or unauthorized system access.

Mitigation Strategies

Update Google Chrome to version 156.0.8078.73 or later immediately. Disable automatic updates temporarily if needed, but prioritize patching. Avoid visiting untrusted websites until updated.
