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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 memory corruption issue that occurs when multiple IOCTL calls are processed using the same buffer file descriptor input. The problem arises because the system accesses memory that has already been freed, which can lead to unexpected behavior or crashes.

Impact Analysis

The vulnerability can lead to memory corruption, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges. According to the CVSS score, it requires local access with high attack complexity and low privileges, but user interaction is required. The impact includes low confidentiality, high integrity, and low availability impacts.
