 - In the Linux kernel, the following vulnerability has been resolved: smb: client: Fix next buffer leak in
 receive_encrypted_standard() receive_encrypted_standard() allocates next_buffer before checking whether
 the number of compound PDUs already reached MAX_COMPOUND. If the limit check fails, the function returns
