Linux Kernel ksmbd Path Handling Vulnerability in VFS Function

A vulnerability in the Linux kernel's ksmbd component was introduced in version 6.1.0-rc1. The issue arises in the 'ksmbd_vfs_kern_path_locked' function, where an error can cause the function to exit prematurely without restoring the original path buffer. This unaddressed change can lead to incorrect path information being used, potentially allowing for unintended file operations.

Impact

Exploitation of this vulnerability could result in file operations being performed with incorrect path information, potentially leading to unintended file creation or modification.
