In the Linux kernel, the following vulnerability has been resolved:

smb/server: fix null-ptr-deref in ksmbd_ipc_tree_connect_request()

See the procedure below:

ksmbd_tree_conn_connect
ksmbd_share_config_get
share->name = kstrdup() // fail
if (!test_share_config_flag(share, KSMBD_SHARE_FLAG_PIPE)) // false
// do not check `share->name`
ksmbd_ipc_tree_connect_request
strlen(share->name) // null-ptr-deref
