In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix use-after-free in i40e_client_subtask()
Currently the call to i40e_client_del_instance frees the object
pf->cinst, however pf->cinst->lan_info is being accessed after
the free. Fix this by adding the missing return.
Addresses-Coverity: ("Read from pointer after free")
