Memory Leak Vulnerability in Linux Kernel for USB Device Management

CVE-2023-53416

What is CVE-2023-53416?

A memory leak vulnerability exists in the Linux kernel's USB management functionality, specifically related to the isp1362 driver. When using the debugfs_lookup() function, the expected cleanup logic is not triggered unless dput() is properly called, potentially leading to gradual memory depletion over time. To address this issue, developers are advised to utilize the debugfs_lookup_and_remove() function, which streamlines the process by incorporating both lookup and cleanup, thereby preventing memory leaks and enhancing overall system stability.
