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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability is a use-after-free issue in the Linux kernel's memory management code. It occurs in the do_fault_around function of memory.c due to a logic error. A use-after-free happens when a program continues to use a pointer after the memory it points to has been freed, potentially leading to crashes or arbitrary code execution.

Impact Analysis

This vulnerability could allow an attacker to escalate their privileges on your system. Since it requires no additional execution privileges and no user interaction, it could be exploited by any local user to gain higher-level access, potentially compromising the entire system.
