Linux Kernel Null Pointer Dereference Vulnerability in TTM Module

CVE-2023-53352

What is CVE-2023-53352?

A vulnerability in the Linux kernel's TTM (Translation Table Maps) module can lead to a null pointer dereference under specific conditions during memory management operations. This flaw arises when the system attempts to access a null pointer while processing the swapout functionality. The lack of a thorough check for null pointers prior to accessing memory can lead to a general protection fault, risking system stability and reliability. Addressing this vulnerability involves implementing additional checks to prevent such dereference scenarios, enhancing the overall security posture of the Linux kernel.
