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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 imgsys component that can lead to escalation of privilege. Specifically, if a malicious actor already has System privilege, they could exploit this vulnerability to gain higher privileges locally without needing any user interaction.

Impact Analysis
