The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the next_ceqe_sw_v2(), hns_roce_v2_msix_interrupt_eq(), hns_roce_ceq_work(), __hns_roce_request_irq() and __hns_roce_free_irq() functions in drivers/infiniband/hw/hns/hns_roce_hw_v2.c. A local user can perform a denial of service (DoS) attack.
