CVE-2024-26743 is a resource-management flaw in the Linux kernel RDMA qedr driver. In the user queue-pair creation path, qedr_create_user_qp() did not release resources already allocated when qedr_init_user_queue() failed. The incomplete error cleanup could leave RDMA uverbs resources allocated and trigger a kernel warning during user-file teardown.
