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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 Modularization component of Google Chrome. It allows a remote attacker to execute arbitrary code within the browser's sandbox by tricking a user into visiting a specially crafted HTML page. The issue exists in Chrome versions prior to 155.0.8059.39.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. Detection involves checking the installed Chrome version.
