CVE-2023-53456

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla4xxx: Add length check when parsing nlattrs
There are three places that qla4xxx parses nlattrs:
qla4xxx_set_chap_entry()
qla4xxx_iface_set_param()
qla4xxx_sysfs_ddb_set_param()
and each of them directly converts the nlattr to specific pointer of structure without length checking. This could be dangerous as those attributes are not validated and a malformed nlattr (e.g., length 0) could result in an OOB read that leaks heap dirty data.
Add the nla_len check before accessing the nlattr data and return EINVAL if the length check fails.
