It will try to lock the same parent and will deadlock.</p> <p>This patch moves the ksmbd_vfs_kern_path_unlock() call to *before* ksmbd_vfs_link() and then simplifies the code, removing the file_present flag variable.</p> <p><strong>Affected:</strong> Linux, Siemens SIMATIC CN 4100</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>smb/server: avoid deadlock when linking with ReplaceIfExists</p> <p>If smb2_create_link() is called with ReplaceIfExists set and the name does exist then a deadlock will happen.</p> <p>ksmbd_vfs_kern_path_locked() will return with success and the parent directory will be locked. ksmbd_vfs_remove_file() will then remove the file. ksmbd_vfs_link() will then be called while the parent is still locked.
