Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Clear all QP fields if creation failed
rxe_qp_do_cleanup() relies on valid pointer values in QP for the properly created ones, but in case rxe_qp_from_init() failed it was filled with garbage and caused tot the following error.
