Exploitability
| 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

This vulnerability is a use-after-free issue in the V8 JavaScript engine used by Google Chrome versions prior to 147.0.7727.55. It allows an attacker who convinces a user to install a malicious Chrome extension to potentially exploit heap corruption through a specially crafted extension.
How can this vulnerability impact me? :
