Summary
enic: Validate length of nl attributes in enic_set_vf_port
Details

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

enic: Validate length of nl attributes in enicsetvf_port

enicsetvfport assumes that the nl attribute IFLAPORTPROFILE is of length PORTPROFILEMAX and that the nl attributes IFLAPORTINSTANCEUUID, IFLAPORTHOSTUUID are of length PORTUUIDMAX. These attributes are validated (in the function dosetlink in rtnetlink.c) using the nlapolicy iflaportpolicy. The policy defines IFLAPORTPROFILE as NLASTRING, IFLAPORTINSTANCEUUID as NLABINARY and IFLAPORTHOSTUUID as NLASTRING. That means that the length validation using the policy is for the max size of the attributes and not on exact size so the length of these attributes might be less than the sizes that enicsetvfport expects. This might cause an out of bands read access in the memcpys of the data of these attributes in enicsetvfport.
