CVE-2022-50127
IBM Linux Kernel Spinlock Uninitialization Vulnerability
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.
