Doc Text:
A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) subsystem, specifically within the mana driver. During an error unwind in the `mana_ib_create_qp_rss()` function, a resource leak occurs where `mana_ib_cfg_vport_steering()` is not properly cleaned up. This vulnerability could lead to resource exhaustion over time, potentially resulting in a Denial of Service (DoS) for affected systems.
