Title
scsi: qla4xxx: Add length check when parsing nlattrs
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.
Severity ?
