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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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-20	The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

Executive Summary

This vulnerability is a use-after-free issue in the Navigation component of Google Chrome on iOS. 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 flaw exists in versions prior to 156.0.8078.47.

Detection Guidance

This vulnerability is specific to Google Chrome on iOS versions prior to 156.0.8078.47. Detection involves checking the installed Chrome version on iOS devices.
