Add length check, modeled after the existing OID_GEN_STATISTICS buffer size check / error return. Discovered by Cesar Cerrudo (IOActive), Ilja Van Sprundel (IOActive), Enrique Nissim (IOActive). v2: add Tested-By: and CVE ID v3: fix size comparison (NDIS_SIZEOF_INTERRUPT_MODERATION_PARAMETERS_REVISION_1) CVE: 2018-11674 Signed-off-by: Gert Doering <firstname.lastname@example.org> Tested-by: Jon Kunkee <email@example.com>
