Vulnerability Title
RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task"
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix the error "trying to register non-static key in rxe_cleanup_task" In the function rxe_create_qp(), rxe_qp_from_init() is called to initialize qp, internally things like rxe_init_task are not setup until rxe_qp_init_req(). If an error occurred before this point then the unwind will call rxe_cleanup() and eventually to rxe_qp_do_cleanup()/rxe_cleanup_task() which will oops when trying to access the uninitialized spinlock. If rxe_init_task is not executed, rxe_cleanup_task will not be called.
