CVE-2022-50127 Information

Description

In the Linux kernel the following vulnerability has been resolved:

RDMA/rxe: Fix error unwind in rxe_create_qp()

In the function rxe_create_qp() rxe_qp_from_init() is called to initialize qp internally things like the spin locks are not setup until rxe_qp_init_req().

If an error occures 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.

Move the spinlock initializations earlier before any failures.
