Description

A flaw was found in the Linux kernel's RDMA (Remote Direct Memory Access) irdma driver. This vulnerability occurs when the `free_qp` completion is not properly initialized before being used during the cleanup process in `irdma_destroy_qp`, specifically if the `ib_copy_to_udata` function fails. An attacker could potentially trigger this uninitialized wait, leading to system instability or a denial of service (DoS).
