CVE-2022-50127
Full vulnerability record from the local CVENow database.
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.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/rxe: Corrección del error de desenrollado en rxe_create_qp(). En la función rxe_create_qp(), se llama a rxe_qp_from_init() para inicializar qp. Internamente, elementos como los bloqueos de giro no se configuran hasta rxe_qp_init_req(). Si se produce un error antes de este punto, el desenrollado llamará a rxe_cleanup() y, finalmente, a rxe_qp_do_cleanup()/rxe_cleanup_task(), lo que generará un error al intentar acceder al bloqueo de giro no inicializado. Se deben adelantar las inicializaciones de los bloqueos de giro para evitar cualquier fallo."
