kernel: information disclosure in hns_roce_alloc_ucontext in drivers/infiniband/hw/hns/hns_roce_main.c
In the Linux kernel before 4.17, hns_roce_alloc_ucontext in drivers/infiniband/hw/hns/hns_roce_main.c does not initialize the resp data structure, which might allow attackers to obtain sensitive information from kernel stack memory, aka CID-df7e40425813.
An information disclosure flaw was found in the Linux kernel. The Infiniband driver does not initialize the resp data structure which allows an attacker to obtain sensitive information from kernel stack memory. The highest threat from this vulnerability is to data confidentiality.
