CVE-2023-54260

Estado: AplazadaSin puntuar—

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

cifs: Fix lost destroy smbd connection when MR allocate failed

If the MR allocate failed, the smb direct connection info is NULL, then smbd_destroy() will directly return, then the connection info will be leaked.

Let's set the smb direct connection info to the server before call smbd_destroy().
