It validates bLength against\nbNumGrpTrmBlock before reading baAssoGrpTrmBlkID[], but not against the\nremaining bytes in the endpoint-extra scan.\n\nA malformed device can therefore make later baAssoGrpTrmBlkID[] reads\nconsume bytes past the walked descriptor.\n\nReject zero-length and overlong descriptors while walking endpoint\nextras.",
